Signs of Heartworm in Dogs

Clinical signs of heartworm disease can be easy to miss and vary depending on the severity of the disease but include:

• Mild cases: May not have any clinical signs, or just a cough.
• Moderate cases: May include a cough, exercise intolerance, and abnormal lung sounds.
• Severe cases: May show abnormal heart sounds, difficulty breathing, liver enlargement, syncope (fainting), fluid accumulation in the abdomen, and death

The onset from the heartworm infection to these clinical signs varies depending on the number of worms in, the body size of the dog, and the dog’s activity level. In general, small, active dogs with higher worm burden have it worse.

How Heartworms Hurt a Dog

The harm that heartworms cause in an affected dog’s body includes:

• Damage to the lungs and the blood vessels in the lungs
• Dead and dying worms can cause thromboembolic events (clots)
• Pulmonary hypertension
• Kidney damage due to accumulation of antigen-antibody complexes
• Large number of heartworms invading the right side of the heart (severe cases)

Heartworms take up much physical space in the heart and interfere with the proper functioning of the tricuspid valve, thus reducing the ability of the heart to pump blood to other parts of the body. This is called “caval syndrome,” and it is characterized by hemolytic anemia, lethargy, weakness, and other signs of right-sided heart failure. Caval syndrome requires urgent surgical extraction of the worms from the heart to save the patient.

Prevent Heartworm

Effective preventatives can prevent this awful disease from affecting the health of your beloved dog. These preventatives are economical and convenient, available in oral, topical, and injectable forms. Some preventatives are combined with flea, tick, and intestinal parasite prevention as well.

Using heartworm prevention as directed by your dog’s veterinarian will help maximize your dog’s life expectancy. More information about heartworm disease, its treatment and prevention can be found at the website of the American Heartworm Society.

Taurine Is Needed For:
1. Healthy heart function
2. As a component of bile acids
3. Retinal function
4. Reproductive health

Dietary Risk Factors for Reduced Taurine Status:

– Low-protein diet (limited taurine precursors)
– Heat-damaged or poor-quality protein sources
– High dietary fiber (i.e., rice bran, beet pulp, cellulose)
– Lamb and rice diets (speculated)
– Plant-based protein sources (peas, lentils, legumes) (speculated)

Possible Risk Factors for Taurine-Deficiency DCM:

BREEDS
American Cocker Spaniel
English Setter
Golden Retriever
Labrador Retriever
Newfoundland
St. Bernard

SIZE
Large-breed dogs
Dogs with slower metabolic rates

DIET
Factors that reduce taurine production
Factors that increase taurine-degrading microbes in the intestine
Factors that reduce bile acid production

In mid-July 2018, the U.S. Food and Drug Administration (FDA) released an alert to veterinarians and pet owners regarding reports of increased incidence of a heart disease called canine dilated cardiomyopathy (DCM). This disorder is characterized by weakening of the heart muscle, which leads to a decreased ability of the heart to pump, and if untreated, to cardiac failure. The reported cases occurred in breeds that are not considered to be genetically predisposed to this disorder.

Further, a significant number of the dogs were found to have reduced levels of circulating taurine in their blood and have responded positively to taurine supplementation. It is speculated that these cases are related to the consumption of foods that negatively affect taurine status, leading to taurine-deficiency DCM. Foods containing high levels of peas, lentils, other legume seeds, and/or potatoes were identified by the FDA as potential risk factors. These ingredients are found commonly in foods that are formulated and promoted as “grain-free.”

As these things go, there followed a lot of hype and a fair bit of hysteria in response. Let us avoid this type of reaction and instead look at the evidence: What do we currently know about the role of diet and taurine in the development of DCM in dogs – and how is it that “grain-free” foods have been recently targeted as a possible dietary cause?

Signs of Dilated Cardiomyopathy (DCM) in Dogs

DCM is a disease of the heart, which causes the heart muscles themselves to weaken, which, in turn, reduces the ability of the heart to pump blood through the dog’s body as it should. The heart becomes enlarged and flabby, and fluid begins to accumulate in the dog’s lungs. As this condition progresses, it causes congestive heart failure.

Early signs of DCM may include:

– Lethargy, decreased energy
– A persistent cough
– Difficulty breathing, rapid or excessive breathing, or seeming shortness of breath
– Episodes of collapse
– Anorexia (chronic loss of appetite)

By the time these DCM signs appear, the disease may already be fairly advanced. That’s why it’s important to make an appointment to see your veterinarian right away if your dog displays any of these signs, or more than one of these signs. Often, owners of middle-aged or senior dogs think that their dogs’ symptoms are “just old age,” but a quick diagnosis and treatment can restore an affected dog’s quality of life to nearly normal – and extend the dog’s life far past an untreated dog’s prognosis.

DCM treatment usually involves medications that help the dog’s heart to contract, slow his rapid pulse, help control the accumulation of fluid in his lungs, and dilate his blood vessels – all actions that will improve the heart’s performance.

What is Taurine? Why Do Dogs Need Taurine?

The nutrient taurine is a unique type of amino acid, called a beta-amino sulfonic acid. It is not incorporated into proteins but rather is found primarily as a free amino acid in body tissues and circulating in the blood. Taurine has many functions, but two that are important for this discussion involve its role in normal heart function and its presence as a component of bile acids, which are needed for fat digestion. Most animals obtain adequate taurine to meet their needs by producing it endogenously (in the body) from two other amino acids, methionine and cysteine.

This means that while most animals require taurine physiologically, most do not have a dietary requirement for taurine. The exception to this rule is the cat. Cats (but not dogs) always require a source of taurine in their food. If they do not have it, one of the diseases that they can develop (and possibly die from) is – you guessed it – DCM.

Taurine-deficiency DCM is well documented in cats. We also know quite a lot about the dietary factors that contribute to this disease in that species. In contrast, dogs (usually) do not require a source of dietary taurine. However, we know that some dogs still develop taurine-deficiency DCM. Why does this happen? The history of DCM in cats can help in untangling what may be occurring in dogs.

Taurine-Deficiency DCM in Cats

Looking back, I cannot avoid a sense of déjà vu. In the early 1980s, veterinarians began reporting increased incidences of DCM in pet cats. By 1987, a role for dietary taurine was suspected. In a seminal study, a veterinary researcher at UC Davis reported low plasma (blood) taurine levels in 21 cats with clinical signs of DCM. 1 When the cats were supplemented with taurine, all 21 recovered from the disease. This discovery led to a series of controlled studies that supported the existence of taurine-deficiency DCM in cats who were fed diets that contained sufficient concentrations of taurine.

What was going on?

It has to do with bile acids. Another role of taurine in the body is that it is necessary for normal bile acid function. Taurine is linked to bile acids in the liver to form bile salts. During digestion, these compounds are secreted into the small intestine, where they function to aid in fat digestion. Animals are very efficient at conserving the taurine that is secreted into the intestine by reabsorbing the bile salts back into the body further down the intestinal tract. This occurs through a process called “enterohepatic reutilization” and prevents a daily loss of taurine in the feces.

Herein lies the problem for cats with DCM: If anything happens during digestion that causes the degradation of the bile salt taurine or that inhibits its reabsorption into the body, more is lost in the feces. If this happens consistently, the cat will experience an increase in his or her daily need for dietary taurine. Simply put – if anything causes the cat to poop out more taurine-bile acid complexes (or their degraded by-products), the cat will be in danger of a taurine deficiency if a higher level is not provided in the diet.

This is exactly what was happening in the cats with taurine-deficiency DCM – and is possibly what we are seeing today in dogs. The difference is that we know what diet factors caused taurine deficiency in cats during the late 1980s. These factors are not yet fully understood for dogs (but we can make a few guesses).

What We Know About Diet and Taurine Status

The studies with cats found that several dietary factors influenced taurine status. These were the level and type of dietary protein, the amount and type of dietary fiber, and the degree of heat that was used during food processing. These factors could affect taurine status in three ways:

1. Bile Acid Binding

Certain fibers and peptides (small protein chains) in the food can bind with bile salts in the small intestine and make them unavailable for reabsorption into the body. This results in an increased daily loss of taurine in the feces and a subsequent increase in daily taurine requirement to replace that loss.

2. Increased Microbial Degradation

Thermal processing of protein (extrusion or canning) can lead to the production of Maillard products – complexes of sugars and amino acids that are poorly digested in the small intestine. The undigested complexes travel to the large intestine and provide an intestinal environment that favors increased numbers of taurine-degrading bacteria. An increase in these bacterial populations reduces the proportion of taurine that is available for reabsorption and reuse by the body.

3. Reduced Taurine Availability

Taurine is found naturally in animal-based proteins but is not found in plant-based protein sources. Therefore, providing diets that include a sufficient level of high-quality animal proteins (that are not heat damaged) should ensure adequate taurine intake.

However, protein that is of low quality or that has been excessively heat-treated will be poorly digested, reducing the availability of taurine and of its precursor amino acids, cysteine and methionine.

In the early 1990s, in response to this new information regarding the interaction of dietary factors and taurine status in cats (and their relationship to DCM in cats), the Association of American Feed Control Officials (AAFCO) increased the recommendations for dietary taurine in extruded and canned cat foods.

Taurine Deficiency in Dogs

Unlike the cat, dogs who are fed diets containing adequate levels of protein should be capable of synthesizing enough taurine from cysteine and methionine to meet their needs. Therefore, a requirement for dietary taurine has not been generally recognized in dogs.

However, there is evidence – evidence that we have had for at least 15 years – that certain breeds of dogs, and possibly particular lines within breeds, exhibit a high prevalence of taurine-deficiency DCM. Genetically predisposed breeds include the American Cocker Spaniel, Golden Retriever, Labrador Retriever, Saint Bernard, Newfoundland, and English Setter.  Although the exact underlying cause is not known, it appears that some breeds have either a naturally occurring higher requirement for taurine or a metabolic abnormality that affects their taurine synthesis or utilization.

A second factor that affects taurine status in dogs is size. There is evidence that a large adult size and a relatively slow metabolic rate influences the rate of taurine production in the body and may subsequently lead to a dietary taurine requirement. It is theorized that increased body size in dogs is associated with an enhanced risk for developing taurine deficiency and that this risk may be exacerbated by a breed-specific genetic predisposition.

There is additional evidence that large and giant breed dogs have lower rates of taurine production compared with small dogs. Ultimately, studies suggest that certain dogs possess a genetic predisposition to taurine depletion and increased susceptibility to taurine-deficiency DCM and that this susceptibility may be related to the combined factors of breed, size, and metabolic rate.

Taurine in Dog Food Diets

The recent spate of cases and media attention to taurine-deficiency DCM in dogs suggests that this is a very new problem in dogs. However, it is not new. A connection between diet and DCM in dogs was first described in a paper published in the Journal of the American Veterinary Medical Association in 2001. What is new is the sudden focus on certain pet food ingredients and the target that appears to have been placed upon the backs of all “grain-free” pet food brands by some bloggers and veterinarians.

Not to put too fine a point on this, but the 12 cases of taurine-deficiency DCM described in the 2001 paper were collected between 1997 and 2001, years before grain-free dog foods had arrived on the pet food scene. Rather than disparage one class or type of dog food (or pet food company), it is more important to look at specific dietary factors that may be involved in DCM in dogs.

Generally speaking, these are expected to be the same as those identified for cats, including low protein levels, poorly processed or heat-damaged proteins (leading to Maillard products), and the inclusion of a high proportion of plant-based protein sources such as peas and legumes.

Over the past 15 years, reduced taurine status in dogs has been associated with feeding lamb meal and rice diets, soybean-based diets, rice bran, beet pulp, and high fiber diets. As with cats, there appear to be multiple dietary (and genetic) factors involved.

For example, it was theorized that the perceived (not proven) association between lamb meal and taurine status was due to low levels of available amino acids present in the lamb meal, or to excessive heat damage of the protein, or to the confounding factor of the inclusion of rice bran in many lamb meal-containing foods. To date, none of these factors have been conclusively proven or disproven. However, the most recent study showed that three types of fiber source – rice bran, cellulose, and beet pulp – all caused reduced plasma taurine levels in dogs when included in a marginally low protein diet, with beet pulp causing the most pronounced decrease.

Complicated? You bet. This is why it is important to avoid making unsupported claims about certain foods and brands. Taurine-deficiency DCM has been around for a while in dogs and continues to need study before making definitive conclusions about one or more specific dietary causes.

Current Considerations of Taurine in Dog Food

We know that any dietary factor that reduces the availability of taurine precursors, binds taurine bile salts in the intestine, or causes an increase in the bacteria populations that degrade taurine, can reduce a dog’s ability to synthesize taurine or will increase taurine degradation and/or loss in the feces. These changes could ultimately compromise a dog’s taurine status (especially if the dog was genetically predisposed) and affect heart health. In extreme cases, as we are seeing, this can lead to taurine-deficiency DCM (see “A Few Things to Know About Taurine” above).

The FDA report identified foods that contain high amounts of peas, lentils, legume seeds, or potatoes to be of potential concern. The FDA also stated that the underlying cause of DCM in the reported cases is not known and that at this time, the diet-DCM relationship is only correlative (not causative). However, this has not stopped various bloggers and even some veterinarians from targeting small pet food companies and/or grain-free brands of food, and implying that these foods, and these foods alone, are causing taurine-deficiency DCM in dogs. Their reasoning is that peas and legumes are present in high amounts in foods that are formulated and marketed as grain-free.

However, the truth is that many companies and brands of food include these ingredients. More importantly, there is no clear evidence showing that a particular dog food type, brand, or even ingredient is solely responsible for taurine-deficiency DCM in dogs.

Rather, it is more reasonable and responsible to speculate that one or more of these ingredients, their interactions, or the effects of ingredient quality, heat treatment, and food processing may play a role. Furthermore, the underlying cause could be the protein, starch, or fiber fractions of these ingredients. As plant-source proteins, peas, lentils, and legumes include varying amounts of starch (both digestible and resistant forms) and dietary fiber. These protein sources are also generally less nutritionally complete and less digestible than are high quality animal source proteins – additional factors that could influence a dog’s ability to both produce and use taurine. Potatoes, in contrast, provide a digestible source of starch in an extruded food but also contain varying levels of resistant starch, which is not digested and behaves much like dietary fiber in the intestinal tract.

Conclusions on Grain-Free Food and DCM

Because any or all of these dietary factors could be risk factors for taurine-deficiency DCM in dogs, and because peas, legumes, and other ingredients identified by the FDA report have not yet been fully studied, the heart of the matter is that no conclusions can yet be made about the underlying dietary cause or causes of taurine-deficiency DCM in dogs.

But given what we do know, we recommend feeding a diet that contains sufficient levels of high-quality, animal-source protein, does not include plant-source proteins as primary protein sources, and does not contain high levels of dietary fiber.

If you are worried about your dog’s taurine status or heart health, whether due to his diet history or physical signs that are of concern, see your veterinarian for a complete physical examination and, if needed, to measure plasma levels of taurine.

Cayenne or chili pepper – the spice that gives Mexican and Sichuan food its heat – is an important medicinal plant. Not only is it Herb of the Year for 2016, it’s good for dogs!

Since 1985, the International Herb Association has announced its Herb of the Year during National Herb Week, which this year is May 1 through 7. The IHA has just published Capsicum: Herb of the Year 2016, a book that reviews chili peppers and their growing conditions and uses, and the organization helps garden centers and herb farms promote its featured plant.

Cayenne (Capsicum annuum) and other members of the Capsicum family are known as chili, chilli, chille, or chile peppers. They belong to the nightshade family, which includes potatoes, tomatoes, eggplant, bell peppers, paprika, pimento, tomatillos, and tobacco.

Native to Central and South America, where they have been cultivated for more than 6,000 years, Capsicum peppers were brought to Europe by Christopher Columbus, whose physician recognized their medicinal benefits. Portuguese explorers continued the trend, and soon hot peppers were grown around the world. Today’s popular varieties include (from mild to hottest) Anaheim, jalapeno, serrano, cayenne, tabasco, Thai, habanero, and ghost peppers.

Rich in vitamins C and A, cayenne also supplies vitamins B3 (niacin), B2 (riboflavin), and B6 (pyridoxine), the minerals iron, copper, and potassium, plus flavonoids and other micronutrients.

Cayenne’s unique ingredient is the alkaloid compound capsaicin (pronounced cap-SAY-sin), which gives hot peppers their heat.

How hot is hot? In 1912, Wilbur Scoville, an American pharmacist, created a test to measure the heat of chili peppers. Now called the Scoville scale, its SHU (Scoville Heat Unit) ratings range from zero (bell peppers) to 30,000 to 50,000 (cayenne), 100,000 to 300,000 (habanero and Scotch bonnet peppers), and up to 2 million for the world’s hottest peppers. Today their heat is measured by High Performance Liquid Chromatography, or HPLC, but the Scoville Heat Units remain popular.

Medicinally, chili peppers are added to herbal formulas in small amounts as a catalyst, a substance that causes or accelerates a chemical reaction without itself being affected. In oral supplements or when added to food, cayenne speeds reactions in the digestive and circulatory systems. Applied topically, it is a rubefacient, which means that it increases circulation to the skin, nerves, and joints, opening subcutaneous capillaries and acting as an analgesic. Wherever applied, cayenne improves the body’s ability to absorb nutrients, fight infection, alleviate pain, and reduce inflammation.

Can Dogs Eat Cayenne?

The key word in any application of medicinal herbs is moderation. This is especially important with cayenne because too much applied topically can damage the skin or, when swallowed, cause severe digestive pain.

Cayenne made headlines in Seattle three years ago when a property manager sprinkled cayenne pepper around her apartment complex, hoping to repel resident dogs whose owners left their waste behind. At least one dog was injured as a result, prompting demands for legal action. Charges of animal cruelty were not filed by the county’s prosecuting attorney because while exposure to cayenne can be painful, it isn’t fatal and doesn’t cause lasting damage. The dog received veterinary treatment and recovered, the property manager apologized, and pet owners agreed to clean up after their dogs.

Capsaicin is the main ingredient in self-defense sprays designed to repel aggressive dogs, bears, coyotes, and other animals. An Internet search will display a variety of sprays and testimonials about their effectiveness. Commercial pepper sprays use oleoresin capsicum or chili oleoresin, an extremely hot pepper extract. Pepper sprays are considered weapons if used against humans, and regulations regarding their legality vary by state according to the products’ strength and size. In some cases, such as when misused by law enforcement officials, pepper sprays have been fatal.

While the taste of pepper doesn’t always deter dogs, less concentrated sprays may prevent Fido from licking and chewing pillows, plants, shoes, or furniture. One popular do-it-yourself repellent spray posted on VetInfo.com combines 1 part cayenne powder with 10 parts water in a spray bottle. “Shake up the mixture to evenly combine the two,” says the instruction page. “Spray just a few sprays of the mixture on the surfaces of the furniture that you’re interested in protecting and in the area surrounding it.”

Cayenne is also recommended as a garden insect, ant, and rodent repellent.

Because cayenne irritates mucous membranes, be careful to avoid your dog’s eyes, nose, genitals, and rectum whenever spraying or applying this herb.

Cayenne Helps Dogs’ Heart Health and Digestion

Can cayenne stop a heart attack? For hundreds of years, herbalists have made this claim, and it appears to be true. Dr. John Christopher, a 20th century American herbalist, used cayenne so often for this purpose that he and his followers made cayenne a routine treatment for heart disease.

As Candace Hunter and Sue Sierralupé wrote in their book Chili Pepper: Naturally Hot Herbal Medicine, “Chili peppers may help stop a crisis in progress. We have historical data to suggest a goodly dose of chili powder swallowed amidst a heart attack can stop the crisis, though we don’t currently have scientific studies to support that. What we do know is chilies can assist the body in healing afterward. Heart surgery patients who experience low circulation, lack of energy, and listlessness are strengthened and invigorated by a daily dose of cayenne pepper in capsule form.”

According to Randy Kidd, DVM, PhD, in his article “Promoting Canine Cardiovascular Health” (WDJ February 2005), “Cayenne is probably the most useful of the systemic stimulants, regulating blood flow and equalizing and strengthening the heart, arteries, capillaries, and nerves. Cayenne is a general tonic and is specific for the circulatory and digestive systems. It has the ability to balance blood pressure, correcting it to a normal range.”

As Dr. Kidd explained, cayenne can be used any time an animal is debilitated, whenever the circulation is stagnant or there is congestion in the body, and whenever there is a lack of energy or vitality. Cayenne is also an outstanding carrier herb, helping in the transport of other herbs and medications to various parts of the body, especially to the heart, stomach, and brain.

Canine heart disease can cause lethargy, weakness, vomiting, a chronic cough, shortness of breath, lameness, and a rapid pulse, all of which may improve when cayenne is added to a dog’s food. Cayenne’s warming effect spreads throughout the body, even to an animal’s extremities, warming a dog’s cold paws and improving the health of veins and capillaries.

In the digestive tract, cayenne improves the body’s absorption of nutrients while reducing gas, flatulence, diarrhea, constipation, and other uncomfortable symptoms. Years ago doctors warned human ulcer patients to avoid hot, spicy foods, but more recent research shows that chili peppers can actually help heal ulcers.

Cayenne is available in capsules, tinctures (liquid extracts), and as the familiar culinary powder. Start with a small amount, such as a pinch of powder or a drop of tincture hidden in your dog’s food or in a capsule that can be hidden in food; two-part gelatin capsules are sold in natural food markets and online. To help prevent digestive discomfort, feed cayenne with a full meal, not on an empty stomach.

Over a period of days or weeks, gradually increase the dose according to your dog’s weight and tolerance. If purchasing cayenne capsules, look for products with a Scoville Heat Unit rating of 30,000 to 40,000, or try Nature’s Way Capsicool controlled-heat cayenne or Solaray’s Cool Cayenne, both of which are advertised as gentle to the stomach. If the recommended dose for adult humans is 2 capsules per day, work up to 1 capsule for dogs weighing 50 to 60 pounds, or, with the help of empty 2-part gel caps, feed half a capsule to dogs weighing 25 to 30 pounds or one-fourth of a capsule to dogs weighing 10 to 15 pounds.

Approximate measurements should work well because individual responses vary and sensitivity to cayenne decreases with daily exposure. If your dog shows signs of discomfort, simply reduce the amount.

You may not have to hide cayenne to get your dog to swallow it, for some dogs are chili heads! Seamus, my husband’s Cairn Terrier, is famous for his enthused vocalizations when he’s offered anything containing hot sauce or cayenne.

Cayenne Topical Treatment for Dogs

It sounds counterintuitive, but cayenne can be an effective first-aid treatment for cuts, scrapes, bites, bleeding nails, mouth lacerations, and other injuries. It is a natural styptic, which stops bleeding on contact, and an analgesic, which stops pain.

When she was a child, a friend was bitten on the leg by her grandmother’s horse. “My grandmother hauled me back to the house,” she says, “filled her hand with cayenne powder and held it against the wound. That hurt for a second or two, but then it stopped bleeding and stopped hurting. The bite was never infected, and it healed in record time without a scar.”

Herbalist Alicia North of Cornwall, Connecticut, has a similar story. Several years ago her cousin snipped the tip of her 14-year-old Terrier’s ear while trimming his hair. “Jack had been bleeding for 10 minutes when she called,” says North, “and none of the remedies she had tried made any difference. She was frantic and without a car so she wanted me to take them to the vet.”

North asked her cousin whether she had any cayenne pepper and then told her to apply it to the cut on Jack’s ear. “She was skeptical and thought that it wouldn’t work and was afraid it would hurt him,” says North. “I assured her that it would help, so she reluctantly agreed and we hung up so she could apply it. Moments later she called back shouting, ‘It worked! I’m so relieved! I thought he might bleed to death. Who knew that spices in my cabinet could be used for anything but cooking?’

“Of course, I knew,” says North, “and I was happy she got such instantaneous results!”

Aches and pains

Some of the most popular treatments for human joint pain and arthritis contain capsaicin.

As the Arthritis Foundation explains on its website:

“Applied as a topical cream, gel, or patch, capsaicin works by depleting the amount of a neurotransmitter called substance P that sends pain messages to the brain. For the first couple of weeks of use, it may cause burning or stinging as substance P is released and ultimately depleted; it must be used regularly to keep substance P from building up again. Many studies have shown that capsaicin effectively reduces pain from osteoarthritis, rheumatoid arthritis, and fibromyalgia. In a 2010 German study, joint pain decreased nearly 50 percent after three weeks’ use of 0.05 percent capsaicin cream.

“Most capsaicin products – such as Zostrix, Zostrix HP, Capzasin-P and others – contain between 0.025 to 0.075 percent concentrations. Apply regularly three times daily.”

Make Your Own Cayenne Liniment

Dogs can enjoy similar results from topical products containing capsaicin. Consider making your own liniment to warm and relax joints and muscles, increase circulation, relieve inflammation, improve flexibility, and speed healing. Traditional recipes combine skin-warming ingredients and therapeutic herbs with cider vinegar.

In a glass jar, combine:

1 pint (2 cups) apple cider vinegar

1 teaspoon powdered cayenne pepper

4 tablespoons dried (or ¼ cup fresh) rosemary

2 tablespoons dried (or 1/8 cup fresh) comfrey leaf or root that has been cut or broken into small pieces

Cover and let stand at room temperature, shaking daily, for a week or longer. Strain before using.

Massage this liniment into tight muscles, bruises, or sore joints, or simply soak a cloth or bandage and hold it on the affected area for as long as possible. You may want to wear latex or vinyl gloves while applying it. Keep this liniment away from eyes and mucous membranes.

Cayenne can be especially helpful in the treatment of pain following surgery, leg amputation, or similar traumas. Taken with food, cayenne increases circulation and promotes tissue regeneration, and applied topically, it helps reduce pain and stimulate healing. According to some reports, human patients with phantom limb pain have been helped by cayenne, as have human and canine patients with nerve damage caused by accident or injury.

Grow Your Own Peppers!

Cayenne and other peppers make attractive garden plants and can be colorful house plants. Most seed catalogs carry a variety of peppers and most garden stores and nurseries offer young plants that transplant easily. Peppers prefer full sun or sun with shade, and overnight temperatures should remain above 55° F (13° C) so that plants produce fruit.

Make Your Own Cayenne Tinctures

You can make your own custom-dose cayenne capsules by partially filling two-part gelatin capsules with cayenne powder. Herb supply companies sell capsule-filling kits to simplify the process.

Make your own cayenne tincture by filling a one-pint or one-cup glass jar with loosely packed fresh cayenne peppers (for best results, cut or chop the peppers as you fill the jar) or loosely packed crushed or broken dried peppers, then add 80-proof vodka or a similar distilled alcohol to fill the jar. Close the lid and leave the jar in a warm but shady location, shaking it every few days for four to six weeks.

When ready to use, strain the tincture through cheesecloth or muslin and pour it into dropper bottles. All the supplies you need are available at natural markets, herbal supply stores, and online. Alcohol tinctures keep for years if stored away from heat and light.

Make Your Own Lactofermented Hot Sauce (AKA Sriracha)

By making a hot sauce, you and your dog can further enjoy the benefits of chili peppers – with just about anything! Start with:

1 pound Fresno or other fresh hot peppers

4 cloves garlic

2 teaspoons salt

2 tablespoons honey or maple syrup

4 tablespoons liquid whey (the clear liquid that separates from live-culture yogurt when you cut it with a spoon and leave it in the refrigerator).

Combine these ingredients in a food processor or blender, or mince the peppers by hand and combine with the other ingredients. Spoon the chili mixture into a glass jar, leaving 1 inch of head space, cover, and let stand at room temperature for 3 to 5 days (longer if the kitchen is cool, less in hot weather).

Transfer to the fridge until ready to use, then set a fine-mesh strainer over a mixing bowl and press the fermented chili through it, or sieve the sauce through a food mill. Pour the strained sauce into a jar or bottle and store in the refrigerator, where it will keep for months. Use in moderation to add warmth and spice to your meals. The taste is uniquely complex and more flavorful than that of vinegar-based sauces. Try adding a drop or two to your dog’s food or use it in place of pepper tincture in two-part gelatin capsules.

Spicy Homeopathy: Cayenne Flower Essence

No discussion of cayenne would be complete without mentioning its use in homeopathy and flower essences. Homeopathic preparations are so diluted that they contain very little of their original ingredient, making them exceptionally safe to use. Homeopathic Capsicum annuum is often prescribed at the 3x or 6x strength for those with poor circulation or who have respiratory or digestive problems. Homeopathic remedies are usually given under the tongue between meals.

Flower essences are made by placing freshly picked blossoms in crystal bowls of pure spring water and leaving them in direct sunlight for three or more hours, after which the flowers are discarded and the energized water is preserved with brandy.

According to the Flower Essence Society, “Cayenne flower essence is a wonderful catalyst whenever we are stuck and need to light a fire to move through obstacles… Cayenne essence can fire up a sluggish will, stimulating activity and movement when our life has stagnated, to move through inertia and challenging obstacles.” It is considered a treatment for apathy and depression.

Some canine massage therapists and acupuncturists incorporate flower essences into their hands-on work. Applying flower essences to a chakra or an acupressure point and then pressing, holding, massaging, or tapping the point can increase the treatment’s effectiveness. Because frequency of application makes flower essences effective, try applying a drop of cayenne flower essence to your dog’s bare skin (nose, paw pads, abdomen, and inside ears) at least twice or three times daily.

The post Cayenne for Canines: They’re Not Too Hot! appeared first on Whole Dog Journal.

A dog’s cardiovascular system is physically and mechanically an incredible assemblage, and its capabilities are almost mystical – literally and figuratively driving the dog’s vital force. However, there are several conditions that can adversely affect the heart in a small percentage of dogs (a much lower percentage than that of humans with heart or vascular disease).

Fortunately, there are also several good, natural, and alternative approaches that can be used to treat canine cardiovascular disease. In my experience, these treatments have been as effective (and safer) than the Western medicine treatments I once used.

Ways to think about the canine cardiovascular system:

Conventional Western medicine views the heart as a simple mechanical pump – a very complex piece of machinery with a simple function as a pumping machine. Other scientists have studied the heart from the perspective of its bioenergetics – studies of the bioelectrical and biomagnetic fields are often centered in the heart, and scientific advances in these areas have led some practitioners to conclude that healthy “cardio-energetics” may be the most important contributor to vibrant overall health.

Many holistic practitioners recognize that the heart is also a primary source of the body’s bioelectric and biomagnetic fields. These energetic fields may be the body’s major source of inner information, necessary for proper functioning of the immune system and other organ systems.

Energy fields may also be responsible for much of the body’s ability to create cellular, organ-related, and whole-body memory fields that are in turn connected to other animals and to the natural environment. According to this line of thinking, since the heart is the primary producer of bioelectric and biomagnetic fields, it may be the organ with the highest intelligence in the form of memory. And the heart is almost certainly the organ that has the most potential for interconnecting with other animals (including humans).

Finally, we now know that the heart’s energetics extend into the surrounding environment almost infinitely. Some traditions have said that it is this heart connection – man to beast – that is the reason the animals were sent here in the first place.

How the Heart of a Dog Works

Okay, enough of theory. Mechanically, the heart consists of two pumps, located side by side and joined along their entire length. Each of these muscular pumping stations is comprised of two chambers, the atrium and ventricle. The atria, located at the cranial part of the heart (nearest the head), are primarily receiving chambers where the blood from veins is collected before its passage into the ventricles. Separating each atrium from its adjacent ventricle is a one-way valve consisting of two or three leaflets, or cusps. The valve on the left has three cusps and is called the tricuspid valve. There are two cusps on the valve between the chambers on the right side of the heart, close together in a shape that resembles a bishop’s miter (thus it is called the mitral valve).

The right side of the heart supplies blood to the lungs where the oxygen from outside air is added and carbon dioxide from cells is expired. This part of circulation is a relatively short course, thus the right side of the heart is not as muscular as the left.

After being aerated by the lungs, the blood circulates into the left atrium (via the pulmonary vein). Then, through the tricuspid valve, it enters the left ventricle. From here the muscles of the ventricle propel the blood through miles of vessels, beginning at the aorta. The heart must not only have enough power of contraction to propel the viscous fluid though miles of vessels, but also maintain a constant beating, as they say, 24/7 for the lifetime of the animal.

There are several factors that control heart rate and rhythm. The sinoatrial (SA) node, located in the muscles of the right atrium, instigates the electrical flow that initiates contraction and propels it across the heart. (Surgically implanted artificial pacemakers can be used to stimulate the SA node when necessary – and yes, this surgery has become relatively common in dogs.)

Heart rate is also under biochemical influence. Stimulation of the sympathetic nervous system (with epinephrine or nor-epinephrine, for example, either provided via injection or from the natural “flight or fight” mechanisms) results in increased heart rate; parasympathetic stimulation slows the heart. Heart rate is also inversely related to systemic blood pressure – when blood pressure increases, heart rate decreases, and vice versa. Blood pressure is further controlled by chemicals (angiotensins) that operate at the kidney to conserve or eliminate fluids in the urine.

The Sounds a Heart Makes

The heart has a voice of its own, and the audible dictation of the cardiac voice is easily heard. The closing of each set of valves is forceful enough to make a slight thupping sound, which is easily heard by placing your ear on your dog’s chest. The first of the thups issues from the tricuspid and mitral valve closures and the second from the pulmonary and aortic valves (the egress valves that prevent regurgitation of blood back into the chambers). The thups create the familiar “lub-dup, lub-dup, lub-dup” sound we are all familiar with.

With a low-tech ear-to-the-chest method you can detect obvious heart murmurs, which I would describe as a “mushing” or “slushing” of the lub-dup sound. Heart sounds are, of course, more apparent when a stethoscope is used to amplify them. Electrocardio-grams, echocardiograms, and MRIs may also be employed for capturing the best possible “sound” of the heart.

Checking Your Dog’s Pulse

A normally functioning cardiovascular system should pump blood to all areas of the body with equal force and rhythm; an animal’s pulse is a reflection of the overall health of the system.

Pulses are especially important in Eastern medicine. Traditionally, the character of the wrist pulse is examined and correlated with a diagnosis that then indicates a direction for treatment. The pulse is taken with three fingers, and three depths of pressure are used for the final determination that combines the nine “readings” into a comprehensive diagnosis.

Our dogs don’t have a good “wrist” site for pulse readings, but some veterinarians have substituted the carotid artery (in the neck) and/or the femoral artery (on the inside of the hind leg) for the traditional wrist readings. My own take on this is that we don’t yet have enough information on these “new” sites to be certain they are giving us readings that are accurate for diagnosis, and I know for a fact that my fingers are not trained well enough to feel the subtleties that a Chinese-trained practitioner has learned with decades of practice.

Electrocardiograms for Dogs

Muscle activity requires a transfer of ions from outside muscle cells into their interior; as these ions are transferred across the cell wall, a minuscule electrical charge is produced. An electrocardiogram (ECG or EKG) records the electrical potential, generated by the electric activity of the heart, taken from electrical leads placed on the surface of the thorax and body extremities. Thus the ECG represents the extracellular electric behavior of the cardiac muscle tissue.

ECGs have become a relatively common form of diagnostic aid, available in many veterinary hospitals. Dog and human ECGs are obtained in the same manner – you get the patient to relax, hook her up to several leads that are connected to the ECG recording machine, take readings on a moving graph paper for several minutes, and interpret the readings.

The heart’s “beat” is created by an electrical activation sequence that proceeds, in a self-propagating wave, from the muscles of the apex of the heart to the muscles at the base. Abnormalities can be detected in the frequency and amplitude of the electrical waves, in the spacing between segments, and in the character of the segments and waves.

However, ECG interpretations are notoriously inconsistent; not even the most skilled interpreters (Board Certified cardiologists) agree with regularity. Numerous studies have shown that family practitioners fail to properly diagnose a high percentage of ECG readings. Also, correspondence between computer models of readings, cardiologists, and general practitioners is not good. I know of no studies that evaluate the reader accuracy of veterinarians, but my guess is that we would fare no better than our physician counterparts.

To summarize, I think it is more important that the practitioner has the ability to get his nose out of the machinery and look at the whole animal. And, until I’ve been able to evaluate the animal’s condition – including his energetics – I always take machine-based results with a grain of salt.

Symptoms of Heart Disease

Common symptoms of heart disease include exercise intolerance; persistent, low-grade coughing; reluctance to move; difficulty breathing or forced respirations; poor blood perfusion (delayed capillary refill time or cyanosis with exertion); and, the animal may sit with his elbows out. Remember that these are the same or similar to the symptoms seen with respiratory disease; it is important to separate these two conditions.

Common Heart Diseases

Heart disease is the number one killer of humans. In dogs, however, heart disease is not nearly so prevalent, affecting only about 10 percent of all dogs. Furthermore, the most common types of heart disease in dogs are not the same as the typical heart conditions in people. Following are some of the more common types of canine heart disease.

Congenital heart disease is perhaps the most common heart disease in dogs with an overall rate of affected animals around 1 percent of the total population. Many diseases such as cardiomyopathy and degenerative valvular disease of small breeds of dogs may have a significant heritable component.

Almost any physical part of the heart may be defective at birth. Symptoms vary with the location of the defect, but most often can be detected by listening for a murmur. The murmur may be characteristic for the type and location of the defect, or more likely, ECGs or other diagnostic aids will be needed to pinpoint the problem. Many animals with defects (and audible murmurs) live a quality life without any signs that a problem exists; others may require surgery to repair the defect.

Valve and endocardial diseases can be caused by any number of conditions including genetic abnormalities; aging, worn valves; and infections (many valve conditions can be traced back to gingival infections; as we advised in “Your Dog’s Mouth“, it’s important to keep your dog’s teeth clean).

Adult heartworms can mechanically interfere with heart valve function. Anytime a heart condition is diagnosed, ask your vet to test for heartworm adults and larvae.

Myocardial disease is also a condition with any number of potential causes including hereditary, nutritional, and infectious. Dilated cardiomyopathy can, for example, be due to a carnitine (an amino acid) deficiency in some dogs that apparently inherit an inability to properly metabolize carnitine. Parvovirus and certain drugs can also induce dilated cardiomyopathy.

Today’s most common form of dilated cardiomyopathy affects only large breed dogs, and tends to be an acute problem that occurs in middle-aged dogs. In this disease, cardiac contractile function is lost, cardiac output decreases, the body compensates by stimulating the sympathetic nervous system – which tries to inappropriately increase heart rate, ultimately resulting in arrhythmias and/or heart failure.

Congestive heart failure can also be caused by a number of conditions. Regardless of the cause of heart disease, the body reacts to a decrease in cardiac output by activating the sympathetic nervous system (increasing heart rate and cardiac contractibility), constricting vessels, and activating the biochemical system (angiotensin) to retain fluids and increase blood pressure. While these mechanisms are life-saving in the short term, if they become prolonged, they produce undue stress for the heart muscle. Unchecked, conditions that affect the function of the heart may ultimately lead to complete or congestive heart failure.

Arrhythmias are abnormalities of cardiac impulse formation, conduction, rate, and regularity. Their causes include poor nutrition, genetic defects, problems with electrical conduction across the myocardium, and biochemical disturbances. Quiet, healthy dogs have a heart rate that is slightly irregular, so diagnosing true arrhythmias requires an ECG or other diagnostic aids, and any diagnosis needs to be correlated with clinical signs – if they exist.

Exercise the Dog, Strengthen the Heart

Oxygen is at the top of the list of nutrients needed by a healthy heart, and exercise is the way to be sure your dog’s myocardium (heart muscle) gets a generous supply. All dogs should have at least a daily 20- to 30-minute aerobic trot-along and a few heart-stimulating romps (after having his heart vet-checked as okay), along with several additional trips to the fireplug during the day.

The second best “medicine” for your dog’s heart is an environment that helps him keep from getting fat. Basic metabolism isn’t all that difficult to understand: Whatever the amount of energy (in the form of calories from food) that goes into the body, it will be utilized first for fueling bodily activities (basic metabolism and muscular activity or exercise), and then, whatever calories that are left over as excess will be deposited as fat. So, to keep it simple, if your dog is putting on weight, you need to either decrease the calories he consumes, or increase his amount of daily exercise – or better yet, do both!

Conventional Heart Treatment

Your conventionally trained vet will be able to tell you a lot about Western veterinary care for your dog’s heart condition – especially if she or he has graduated from vet school in the past decade – so I won’t use much space discussing conventional care. Conventional Western treatment for cardiac conditions, of course, depends on the condition, but a normal protocol would include some or all of the following:

• Diuretics – to remove excess body fluids present because the heart isn’t moving them along properly.

• Digitalis (or digoxin) – to improve heart function

• Vasodilators – to lower blood pressure. Nitroglycerine might be the drug of choice here, or others may be selected.

Alternative Care for the Heart

While Western medicine requires a definitive diagnosis before a proper treatment protocol can be initiated, most alternative medicines are prescribed for symptoms. Furthermore, most of the natural and alternative remedies used have a wide range of effectiveness for many conditions, and they are typically safer (although perhaps not as potent) as conventional drugs.

Heart-Healthy Nutrition

The best preventative “medicine” you can provide for your dog is heart-healthy nutrition. The cardiac-impaired patient should be on a well-balanced diet that helps maintain his ideal body weight. If your dog is overweight, a mild reduction in food intake is recommended – about 80 to 99 percent of caloric maintenance levels. Ideal weight reduction would amount to a slow, steady weight loss of 1 to 3 percent of total body weight per week. For specifics on a weight-loss program, see your vet.

Many heart patient dogs are older animals who also suffer from kidney and/or liver disease. Years ago, very low-protein (14 to 15 percent) diets were automatically prescribed for dogs with kidney or liver disease, as high protein diets force the kidney and liver to work overtime. Unfortunately, some of these animals, particularly those who are on this diet long term, may develop malnutrition. Today, we prescribe a diet with a slightly higher level of protein, with a special emphasis on the protein’s quality (high biologic value) and digestibility for these dogs.

Dogs with severe and chronic heart disease may also show signs of protein-energy malnutrition, seen as loss of both fat and lean body mass (“cardiac cachexia”). A diet containing high-quality protein will help prevent this condition. B vitamins, choline, and inositol are good supplements to help maintain a healthily functioning liver.

Diets high in salt may increase blood pressure, which in turn adds to the physical stress to the heart. Low salt diets that include 0.05 to 0.5 percent (dry matter) sodium are indicated for the canine cardiac patient. In addition, stop sharing any salty human treats such as potato chips, pretzels, processed meats, canned fish and vegetables, and cheeses. Many commercial dog treats also contain high salt levels, so check the label for salt content when feeding or treating your cardiac-compromised canine.

Whenever we supplement the diet, the most important consideration is to maintain a balance of nutrients. One of the first things I do with new clients is to look at the supplements they already give their dogs. Invariably, there are several products that contain the same or similar nutrients. Overdoses of any substance can be dangerous. And digestion, assimilation, and metabolism often depend entirely on the overall balance of several independent nutrients. Talk to your vet; don’t just “wing” it!

Human patients with chronic cardiac failure are frequently deficient in iron, zinc, magnesium, potassium, chloride, and B vita-mins. Although similar problems are not well documented in dogs, B-vitamin supplementation is recommended, provided in a balanced vitamin-mineral supplement. Vitamin E (along with a balanced level of selenium) has been shown to be beneficial for heart muscles in many people, and vitamin C has healing activity and helps maintain the integrity of the heart walls and blood vessels.

Some types of diuretics cause decreased levels of potassium (hypokalemia), which predisposes the patient to digitalis intoxication and to cardiac arrhythmias. If your dog receives a diuretic medication, check with your vet to see if potassium supplements are recommended. Also see dandelion (in the herbal section, below) for a natural diuretic that restores potassium levels.

At least two amino acids, taurine and carnitine, have been directly implicated in heart conditions in some species. There is evidence that carnitine may be involved in occasional canine heart problems.

L-carnitine (the bioactive form) is similar to the B vitamins, and its main function is to help transport fatty acids, which are then burned within cells to provide energy. Carnitine deficiency is usually the result of genetic factors that cause the patient to require higher amounts of carnitine than normal. Deficiencies at the cellular level may contribute to some types of muscular problems including muscular dystrophy and cardiac myopathy.

The normal dog’s body can manufacture carnitine if sufficient amounts of iron, vitamins B-1, B-6, and C and the amino acids lysine and methionine are available. Carnitine is naturally available from meats and other animal-origin foods.

Coenzyme Q-10 (Co Q-10) is a vitamin-like antioxidant substance whose actions in the body resemble those of vitamin E. Co Q-10 plays a critical role in the production of energy in every cell of the body, aids circulation, stimulates the immune system, increases tissue oxygenation, and has anti-aging effects. It also counteracts histamine and is thus beneficial for treating allergies, asthma, arthritis, or respiratory disease. It has been shown to be effective in reducing mortality in experimental animals afflicted with tumors and leukemia, and it may reduce the side effects of cancer chemotherapy.

Co Q-10 has a great impact on heart tissue, and it has become the supplement to consider for treating and preventing heart disease. Its mode of action is to strengthen the heart muscles, and it has proven beneficial (in humans) for treating congestive heart failure and high blood pressure. It is thus used for almost any heart condition.

Natural sources high in coenzyme Q-10 include mackerel, salmon, and sardines, and it has also been found in beef, peanuts, and spinach. The amount of Co Q-10 present in the body declines with age, so the aging dog is a prime candidate for supplementation. It is oil soluble and should be taken with oily or fatty foods.

Fatty acids are the basic building blocks for fats and oils. Those that can’t be made by the body and that are necessary for health are called essential fatty acids (EFAs). Every living cell of the body requires EFAs for rebuilding and producing new cells. They are also involved in the production of prostaglandins, the chemical messengers and regulators of various body processes. In addition, EFAs are beneficial for healthy skin and hair, for reducing blood pressure, as an aid in the prevention of arthritis, for lowering cholesterol, and to reduce the risk of blood clot formation.

The two basic categories of essential fatty acids are Omega-3 and Omega-6. Omega-3 EFAs include linoleic and gamma-linolenic acids; they are found in raw nuts, seeds, and legumes and in unsaturated vegetable oils from borage, grapeseed, primrose, sesame, and soybeans. Omega-6 EFAs, including alpha-linolenic and eicosapentaenoic acid (EPA) are found in fresh deepwater fish, fish oil, and certain vegetable oils including canola, flaxseed, and walnut. Note that these oils need to be consumed in liquid form, they don’t tolerate heat, and they are subject to spoilage.

Once again, consult with your holistic veterinarian to ascertain proper dosages of any supplements. Dosages should vary for each individual patient and will depend on whether maintenance or therapeutic dosages are desired. Also, you should be absolutely certain you provide the supplements in a balanced format for proper absorption, assimilation, and metabolism, and for correct interaction with other supplements.

Herbal Remedies for Dogs with Heart Problems

Herbal medicine has much to offer canine cardiac patients. Most herbal remedies convey mild, supportive care without appreciable adverse side effects.

Hawthorn (Crataegus oxyacanthoides) is the queen of all cardiac tonics, with ample scientific evidence to justify its claims. Hawthorn has many beneficial effects on the heart including enhancing oxygen utilization by the heart muscles; improving blood supply to the heart by dilating the coronary arteries; improving metabolism in the heart, which increases the heart’s force of contraction; helping stabilize cardiac activity, thus eliminating some types of rhythm disturbances; and reducing blood pressure.

In short, hawthorn acts on the heart in a normalizing way, by either depressing or stimulating the heart’s activity, depending on the need. It is thus an excellent herb to consider whenever a general tonic is needed for the circulatory system. It is used for treating heart failure or weakness, congestive heart failure, arrhythmia, and high blood pressure (due to its tonic activity, it will normalize high or low blood pressure).

In addition, hawthorn helps stabilize collagen, perhaps via its synergistic activity with vitamin C. Collagen stabilization helps make capillaries less permeable and fragile. Hawthorn reduces destruction from any inflammatory process such as periodontal disease, arteritis, and arteriosclerosis. It can thus be used as an aid for treating the cartilage deterioration and ligament instability associated with arthritis.

Compared with digitalis, in general, hawthorn is safer and milder in activity. Digitalis has a direct action on the heart; hawthorn lowers blood pressure by dilating the peripheral vessels, thus preserving critical reflexive blood pressure regulation. Hawthorn does not cause the cumulative effects that occur with digitalis.

Hawthorn can be used by itself or in combination with digitalis, where it has a synergistic effect. With the combination, your practitioner may be able to lower the digitalis dosage to about one-half the normal dose. Further, the herb may partly ameliorate undesirable effects of digitalis.

Hawthorn toxicities have not been reported, although you should use caution if it is being used along with digitalis, and at least one report recommends that it not be used along with beta blockers as it may antagonize them.

I like it that hawthorn was once considered a sacred herb. Hawthorn has long been recognized as a healer of that part of the heart that is not simply mechanical or biochemical – a healer of the spirit and soul that may reside within our hearts.

Motherwort (Leonurus cardiaca) is an excellent herb often found growing as a weed along fence rows or at the edges of lawns. Motherwort has three primary actions: as a cardiac tonic; sedative and antispasmodic; and as a tonic that helps stabilize the female reproductive tract. It is thus indicated for all heart conditions, but especially for those that are associated with anxiety and tension. It is often used to treat increased heart rates.

Motherwort has been shown to improve metabolism in the heart, reduce heart rate, increase coronary perfusion, inhibit platelet aggregation, and may cause mild hypotension. Sensitive people may develop a contact dermatitis from the plant, but other toxicities have not been reported.

If the heart is not functioning properly, fluid can build up in the lungs, causing respiratory distress. Enough of a fluid backup can cause edema (water collection at various parts of the body). Dandelion root (Taraxacum officinale) is an excellent diuretic and general tonic, and has beneficial activity for the liver and gall bladder. In animal studies, dandelion has proven to be a strong diuretic, comparable to the action of the drug, furosemide. However, while furosemide depletes potassium from the body, dandelion, with its high levels of potassium, re-supplies it naturally. Dandelion is a very safe herb to use; virtually no adverse side effects have been reported.

Cayenne (red or chili pepper, Capsicum spp.) is probably the most useful of the systemic stimulants, regulating blood flow and equalizing and strengthening the heart, arteries, capillaries, and nerves. Cayenne is a general tonic and is specific for the circulatory and digestive systems. It has the ability to balance blood pressure, correcting it to a normal range.

As a stimulant, it can be used any time an animal is debilitated – whenever the circulation is stagnant or there is congestion in the body and whenever there is a lack of energy or vitality. Cayenne is also an outstanding carrier herb, helping in the transport of other herbs and medicines to various parts of the body, but especially to the heart, stomach, and brain. Very high doses over long periods can cause internal problems such as chronic gastritis, kidney and liver disease, and neurological effects.

I find that many pets (cats included) really like food seasoned with a pinch of one of the many kinds of cayenne, and since there are at least 1,700 different pepper varieties, you should be able to fine one that your dog enjoys.

Other heart-healthy herbs to consider:

• Yarrow (Achillea millefolium) is a standard herb for treating fevers, and it is used externally as a wound-healing aid. It also lowers blood pressure and tones the blood vessels.

• Rosemary (Rosmarinus officinalis) has long been considered to be an effective memory aid, and it is used to stimulate the appetite and to promote digestion. It also stimulates blood circulation, and it is a good tonic herb for the aging dog.

• Ginkgo (Ginkgo biloba) improves brain function by enhancing blood flow to the brain, stabilizing cellular membranes, and improving oxygenation of tissues. These cell-level activities may also be directly beneficial to heart tissues.

Homeopathy and the Heart

Homeopathic remedies are used to treat the symptoms of disease, and several have been used to help with heart conditions. Crataegus may used in cases of heart weakness and also for irregular heartbeat, myocarditis, and edema. For arrhythmia Convallaria is a good choice, and for valvular disorders Adonis vernalis may be helpful. Rumex may be helpful for the long-standing heart disease in older animals, and Spongia tosta is also a good remedy for chronic cases where the respiratory pattern is gasping and violent.

Flower Essences for Heart Health

Flower essence remedies are used to alleviate emotional problems. Fix the emotions, the theory goes, and the physical problems will also clear up. Flower essences that may be beneficial for heart problems include mimulus (also a remedy to restore courage in the animal that has a fear of known things or is shy or timid); oak (the remedy that restores resilience, endurance, strength, and stamina, and is especially indicated for dogs dealing with chronic and serious heart disease); and Rescue Remedy (the emergency remedy to be used for any acute event that may be related to the heart).

Improving Matters

No matter what medical approach we take to try to help the heart patient – whether it’s Western, alternative, or a complementary mix – we may do no better than alleviating the worst of the symptoms. And if the problem is structural (a physical defect in the heart, for example), medicines will not fix the defect; the best we might accomplish is to enhance the dog’s quality of life. However, in the case of debilitating cardiac conditions, that’s a lot! As always, I suggest that guardians explore all their medical options for care and treatment of their canine companions.

YOUR DOG’S HEART HEALTH: OVERVIEW

1. Have your dogs examined by a holistic veterinarian annually. Discuss any and all nutritional supplements with him or her.

2. Make sure your dog exercises daily, for at least 20-30 minutes.

3. Feed your dog a food that contains the highest-quality protein you can afford.

4. Two words: Hawthorn tea.

FEEDING HAWTHORN TO DOGS: OVERVIEW

1. Consider hawthorn as a supplement for a dog with heart problems – especially high or low blood pressure, and arrhythmia.

2. Use hawthorn as a tonic for older dogs, in conjunction with an improved diet.

As a traveling, lecturing herbalist, I often hear the question of whether herbs might be helpful in treating old or debilitated dogs with chronic disease.

My answer: Yes – especially when used to supplement a good, natural diet and to strengthen or “tonify” the body’s natural healing functions. When used in this capacity, we refer to herbs as herbal tonics.

Unlike most conventional drugs, tonic herbs do not suppress or replace natural functions in the body. Instead, they serve to improve the body’s efforts to stay healthy. Tonic herbs are neither drug-like remedies nor foods, but stand somewhere in between, providing supplemental measures of support that help bridge the gaps between what a body needs from diet and what it needs in terms of specific, added support.

Most tonic herbs do their work by providing special nutrients, enzymes, and other chemicals that the body needs to bring deficient or overtaxed organs and systems into higher levels of efficiency.

Hawthorn (Crataegus species), a tonic herb that has been used for centuries to improve cardiac function and output, is a classic example. Hawthorn does not initiate any immediate changes in heart function, but does so very gently over time, without adding stress or interfering with other body functions. Hawthorn helps support the heart and cardiovascular system in ways that no food or drug can.

Hawthorn is a Preventative Heart Tonic

Hundreds of scientific studies have validated hawthorn’s usefulness as a heart tonic.

It is well known that hawthorn dilates both coronary vessels and vessels of the brain, helping to increase circulation and the transport of nutrients and oxygen throughout the body.

It accomplishes this in a very effective and unique fashion: while it acts to dilate major vessels, it also increases blood flow from the heart to compensate for any reduction of arterial blood volume. In other words, it helps the body push more blood around by increasing cardiac output and decreasing blood flow resistance in the arteries, i.e., more blood flow at less pressure. This has been shown in studies performed with dogs, especially when used in small doses over an extended period.

Hawthorn also serves as a blood pressure regulator. Although the mechanisms of this activity baffle herbalists and scientists alike, the herb tends to gently elevate low blood pressure, and decrease high blood pressure. This is really quite amazing, especially when we consider the fact that hawthorn does this while increasing cardiac output. By helping with dilation of coronary arteries and strengthening heartbeat, hawthorn improves blood circulation without adversely effecting blood pressure.

Another well-documented benefit of hawthorn is its ability to steady and strengthen a weak or erratic heartbeat – such as that of elderly or energetically challenged dogs. In human applications hawthorn has been used as an alternative to antiarrhythmia drugs like digitalis, and to improve the effects of that and other cardiac drugs.

Hawthorn is also a great antioxidant. It scavenges free radicals that rob the blood of oxygen and may lead to various forms of vascular disease. Herbalists also use the herb to lower blood cholesterol.

All of these activities are largely attributed to a vast assortment of flavonoid constituents held within the berries, leaves, flowers, and twigs of hawthorn. Although flavonoids are also found in many other kinds of fruits (especially raspberries, blueberries, and other red or blue fruits), hawthorn is an especially rich source.

Studies have shown that flavonoids are essential in maintaining disease resistance and the integrity of smooth muscle tissues throughout the body. Some studies even suggest that hawthorn may help prevent myocardial damage in situations where the heart muscle is subjected to physiological stress. This means that animals such as race horses or working dogs who are constantly under cardiovascular stress will likely find preventive benefits from daily supplements of hawthorn.

And to top everything off, hawthorn is very, very safe. In fact, in the hundreds of animal studies that have been conducted with this herb over the past 100 years, hawthorn has shown extremely low toxicity in every animal tested. I place the risk of hawthorn berry toxicity on about the same level as that presented by rose hips, raspberries, or blueberries. In other words, I consider them all as medicinal foods.

Daily Hawthorne Use Shows Cardiac Improvements

It stands to reason that this cardiovascular tonic is useful in the daily care of any older dog, but especially those who suffer from chronic heart problems such as arrhythmia, congestive heart failure, postsurgical dysfunction, or other cardiac anomalies that have weakened the heart’s ability to pump blood.

I consider hawthorn to be strongly indicated in virtually any case where damage to the heart muscle has resulted from heartworm infestation, bacterial or viral infections, or protracted chemotherapy.

I also find hawthorn useful in cases of renal failure, especially in early stages of the disease. When combined with ginkgo biloba (for small capillary circulation) and herbs that improve urinary function, hawthorn may be useful for getting more blood and oxygen into renal arteries and smaller vessels of the kidneys. This, in theory, is thought to slow degeneration of whatever healthy tissue remains in the diseased organs.

What is Hawthorn, Anyway?

Hawthorn is small deciduous tree or large shrub (up to 16 feet tall) that is easily recognized and quickly remembered by its nasty one- to three-inch curved thorns, which are strategically spaced along the branches – often at eye-level! The alternate leaves are narrowly fan-shaped or ovate and are presented on short petioles. The margins of the one- to two-inch-long leaves are toothed, with tips all pointing distinctly forward.

Blooms appear on the hawthorn plants from around April through June. The white, quarter-inch flowers are presented in flat, terminate clusters; each blossom with five petals and numerous stamens. When in full bloom, the blossoms often have an unpleasant “dead” odor. In late summer the flowers are replaced with clusters of red to black berries, each containing two to five seeds.

The Crataegus genus is large and varied, with hundreds of species (all of which readily hybridize) in North America. Most species are found in riparian thickets, where they serve as important forage and nesting habitats for birds and other wildlife. While Crataegus oxyacantha and C. monogyna are the primary hawthorns of commerce, C. douglasii is one of the most common and widespread wild species of North America. While very little study has been done to ascertain which species are most useful, most herbalists will agree that all of them hold therapeutic value.

How to Feed Hawthorn to Your Dog

When combined with a good natural diet and other tonic herbs, hawthorn will act exactly as an herbal heart tonic should – to fill the special cardiac needs in the golden years of an animal’s life.

Other tonic herbs can be used in combination with hawthorn to round out the supplemental needs of older animals. These might include ginkgo or yarrow (for strengthening capillary walls and improving blood supply to the kidneys and extremities); garlic (for added antioxidant and immune system support); alfalfa and red clover (to nourish the blood, increase appetite, and raise energy levels); dandelion leaf (to assist in the removal of excess water); and oat tops (as a nervous system tonic).

In the natural pet product industry, the berries of hawthorn are the most commonly used part of this plant. This is probably because they make such palatable medicine. However, the flowering branch ends (leaves, flower buds, twigs, thorns and all) are fine medicine too, and can be clipped into small pieces and brewed into a decoction (a simmered tea). However, unlike the berries, the “twig tea” tastes awful!

If you are lucky enough to have a hawthorn tree near your home and a dog that likes red fruit, you can pick the ripe berries and feed them as tonic treats.

Or, when the berries become fully ripe, they can be picked, dried on a clean sheet of paper, and ground with a mortar or pestle (be forewarned that they burn out small coffee grinders!) into a coarse powder. The powder can then be added to your companion’s diet at a rate of one teaspoon per pound of food fed each day.

If your pup won’t eat the berries either way, try making a tea (with about a teaspoon of dried berries and a cup of hot water) and pouring it over his food. If that doesn’t work, you can use gel caps wrapped with expensive, imported Brie cheese (just kidding!). Better yet, you can use a liquid hawthorn tincture (one-half tsp. for small dogs; one-half to one tsp. for larger dogs). Alcohol-free, glycerin-based tinctures are quite sweet and easiest to feed.

The post Hawthorn Herb Improves Cardiac Function in Dogs appeared first on Whole Dog Journal.

Centuries ago, people in the fishing communities of Scotland, Greenland, Iceland, and Norway thrived despite their intensely cold winters by taking a daily dose of cod liver oil. By the 1800s, folks around the world were taking a tablespoon a day because it relieved aching muscles, stiff joints, and rheumatism in addition to improving overall health.

In the 1950s, scientists discovered that essential fatty acids in cod liver oil improve heart and circulatory system health.

The vitamins in cod liver oil have been proven essential for growth, healthy bones, proper development of the brain and nervous systems, normal sexual development, and a strong immune system.

And scientists are still studying cod liver oil. In 2002, researchers in Wales found that cod liver oil’s omega-3 fatty acids disable enzymes that destroy cartilage. As a result, cod liver oil delays and even reverses the “irreversible” destruction of joint cartilage and inflammatory pain associated with arthritis.

All of cod liver oil’s human benefits are shared by dogs, including improved memory function, reduced behavioral disorders, and enhanced immunity.

“It’s definitely a miracle food,” says nutritionist Krispin Sullivan, CN. “There is hardly a disease in the books that does not respond well to treatment that includes cod liver oil, and not just infectious diseases but also chronic modern diseases like heart disease, cancer, and diabetes.”

How Did We Discover Cod Oil’s Benefits?

In Europe and North America, rickets used to be a common illness. Without vitamin D, calcium salts are not deposited in bones in sufficient quantity to make them rigid. As a result, soft bones bend out of shape.

In 1892, a British scientist discovered a connection between the geographic distribution of rickets and sunlight. The more sunlight a region had, the fewer rickets cases it reported. In 1913, researchers at the University of Wisconsin showed that lactating goats kept indoors lost substantial amounts of skeletal calcium, while those kept outdoors did not. (Osteomalacia, or adult rickets, is a softening of bone caused by progressive decalcification.) Six years later, a German scientist cured children of rickets using artificially produced ultraviolet light. Two years after that, researchers at Columbia University cured children of rickets by exposing them to natural sunlight.

Though the sunlight connection was well established, no one understood how or why it worked. Then in 1918, British physician Sir Edward Mellanby, who was searching for a nutritional cause of rickets, tested oat porridge, the staple food of Scotland, for its effect on bone health. His test subjects were dogs. He fed them nothing but oats and kept them indoors throughout the experiment, and they promptly developed rickets. When he cured the dogs by feeding them cod liver oil, Mellanby assumed that the oil’s newly discovered vitamin A had repaired their bones. This was a logical assumption, for cod liver oil is the world’s most concentrated food source of vitamin A, containing more than four times the vitamin A of beef liver, the next most concentrated source.

However, at Johns Hopkins University, Professor E.V. McCollum proved that this was not the case. The cod liver oil he heated and aerated to destroy its vitamin A content no longer cured night blindness (which vitamin A prevents), but it did continue to cure rickets. This meant that cod liver oil must contain a previously unknown essential nutrient. In 1922, McCollum published his results and, in keeping with the practice of naming vitamins in alphabetical order, called his discovery vitamin D. Later research proved that sun exposure on the skin produces vitamin D, hence its “sunshine vitamin” nickname.

Newer Research on Cod Liver Oil

Although cod liver oil is not as widely used as it was a hundred years ago, it is still easy to find, inexpensive, and even more beneficial than early researchers realized.

For example, cod liver oil greatly improves heart function and treats it even in advanced stages by healing the lining of damaged arteries. Cod liver oil’s omega-3 fatty acids and vitamins A and D facilitate mineral absorption, improve muscle function, and support elasticity of the blood vessels. In addition, inflammation-reducing prostaglandins made from EPA (one of cod liver oil’s essential fatty acids) help inhibit inflammatory responses in the arteries.

Cod liver oil’s vitamin A strengthens the immune system, fights infection, heals the skin, repairs the digestive tract, is essential to the formation of bones and teeth, aids in fat storage, stimulates new cell growth, and improves the body’s utilization of protein. Cod liver oil taken by nursing mothers improves the fatty acid profile of breast milk to promote optimal brain development, and it increases vitamin A levels, which help prevent infection. However, cod liver oil does not increase the vitamin D content of breast milk.

In more than 40 human trials, vitamin A has been shown to reduce morbidity and mortality of infants and children, and cod liver oil was the supplement of choice in many of these trials. “Books on feeding infants published in the 1930s and 1940s routinely recommended cod liver oil,” says Sullivan, “starting with 1 teaspoon at the age of three weeks. It was Dr. Spock who threw this wisdom out the window by recommending vaccinations instead of the powerful nutritional support of cod liver oil.”

The easiest way to give cod liver oil to infant puppies is to use an eyedropper to place a few drops on the mother’s nipples or directly into the puppies’ mouths. Start with 1 drop per 4 ounces (¼ pound) of body weight per day. As puppies grow, give 3 to 4 drops per pound of body weight. Puppies weighing 6 pounds should receive 1/8 teaspoon per day, and pups weighing 12 pounds need ¼ teaspoon per day.

Like our human population, America’s dogs are increasingly susceptible to obesity, insulin resistance, and adult-onset diabetes. Cod liver oil has been used in clinical trials on humans with insulin-dependent and non-insulin-dependent diabetes. In both conditions, cod liver oil improved glucose response and other markers of the disease. In 2001, Finnish scientists reported that infants who received vitamin D were much less likely to develop juvenile or adult-onset diabetes than those who did not. In addition, vitamin A in cod liver oil helps promote healing and protects the retinas of diabetic patients.

Even colitis (inflammation of the colon) responds more effectively to the type of omega-3 fatty acids in cod liver oil than to medication. And let’s not forget cancer, whose epidemic rise coincides with America’s declining cod liver oil consumption. Vitamin A has been part of nearly every nutritionally based cancer therapy.

How You Administer Cod Liver Oil Matters

Eating fish, even oily fish, will not provide the levels of nutrients found in cod liver oil, and taking fish oils is not the same as taking cod liver oil. Salmon oil, which has significant health benefits, has only one-fifth the potency of cod liver oil.

Most cod liver oil has a vitamin D to vitamin A ratio of 1 to 10. If a teaspoon of cod liver oil contains 500 International Units (IU) of vitamin D, it contains about 5,000 IU vitamin A. However, some brands, such as Carlson Labs, which is sold in health food stores, have a much lower vitamin A ratio. One teaspoon of Carlson Labs cod liver oil contains 500 IU vitamin D and only 1,250 IU vitamin A. This proportion helps prevent vitamin A toxicity, especially in dogs who eat large amounts of beef liver or receive vitamin A from other sources.

Heavy metals and other contaminants are always a concern when dealing with ocean fish, but all cod liver oil sold in the United States is tested according to protocols of the Association of Analytical Communities. It must be found free of detectable levels of 32 specific contaminants, including mercury, cadmium, lead, and PCBs, before it can be imported.

Cod Liver Oil Dosage and Cautions for Dogs

A teaspoon of cod liver oil contains 45 calories. The recommended cod liver oil dose for dogs who do not receive other sources of vitamins D and A is ¼ teaspoon for dogs weighing 10-15 pounds; ½ teaspoon for 25-pund dogs; 1 teaspoon for dogs weighing 50 pounds; 1½ teaspoons for 75-pound dogs; and 2 teaspoons for dogs weighing 100 pounds. These doses have been used for decades with dogs who fast one day per week (no cod liver oil on fast days) as well as dogs who are fed every day.

But for dogs who eat a commercial diet, cod liver oil supplementation can be dangerous, because commercial pet foods contain vitamins A and D. In most cases, these vitamins are synthetic rather than from food sources. Although the synthetic vs. food-source debate continues to be lively, a growing number of researchers and nutritionists have found that food-source vitamins are more effective at smaller doses because they are more easily assimilated than synthetic vitamins.

Dogs fed a home-prepared diet derive far more than vitamins A and D from cod liver oil, which is itself an argument for home feeding. Another argument is Sir Edward Mellanby’s canine rickets experiment. During his research, Mellanby discovered that phytic acid in grains and legumes blocks mineral absorption. Grain-based foods can be difficult for dogs to digest, and can contribute to deficiencies of zinc and other minerals.

Before deciding on the dose to use, consider how much sun exposure your dog receives, the time of year, and your location. Dogs who live outdoors in the southern United States may absorb vitamin D by grooming themselves and other dogs, even though they do not absorb it directly through the skin the way humans do.

In America’s middle latitudes, the sun does not produce vitamin D throughout the year. For example, in New York City, the sun’s angle prevents vitamin D production from October through April. Dogs who live outdoors during summer months in New York City and similar latitudes may need less (such as half the recommended dose) during the summer. Dogs living in New England, other Northern states, and Canada receive little or no vitamin D from the sun even in the middle of summer. They will not require a dose reduction.

Vitamins D and A are toxic in excess, so overdoses must be avoided. Many puppies and dogs have died from swallowing tubes of vitamin D-based medications for psoriasis and other human skin conditions. If you spill cod liver oil, don’t let your dog lick it up. If you feed a commercial pet food that contains vitamins A and D, don’t give your dog cod liver oil in addition.

Last, feed saturated fats like butter or coconut oil in combination with cod liver oil. The body needs saturated fat in order to absorb and assimilate the fat-soluble vitamins (A, D, E, and K). Flaxseed oil and other vegetable oils do not provide saturated fats and do not enhance the absorption of fat-soluble vitamins. An easy rule of thumb is to give equal amounts of cod liver oil and saturated fat, so for every teaspoon of cod liver oil, give your dog a teaspoon (or more) of butter or coconut oil.

Who hasn’t heard of CoQ10? A powerful antioxidant, coenzyme Q10 is one of America’s most popular supplements. Literally every cell of the body contains CoQ10. In fact, its other name is ubiquinone, reflecting its widespread distribution in the body.

CoQ10 is most concentrated in the mitochondria, the portion of cells that produce energy. The heart and liver contain more mitochondria per cell than other body parts and thus contain the most CoQ10. Human and animal deficiencies are not yet well understood, but low CoQ10 blood levels have been reported in patients with heart disease, gingivitis (inflammation of the gums), morbid obesity, muscular dystrophy, and AIDS.

As a nutritional supplement for humans, CoQ10 is used to treat angina, congestive heart failure, high blood pressure, mitral valve prolapse, diabetes, gum disease, Alzheimer’s disease, chronic obstructive pulmonary disease (COPD), AIDS, and infertility, and to improve athletic performance. In dogs, it is most widely prescribed for congestive heart failure and gum disease.

CoQ10’s Effect on Dogs

Not everyone agrees that CoQ10 works. Bruce West, DC, dismisses CoQ10’s popularity as unsubstantiated hype. In the November 2000 edition of his popular Health Alert newsletter, Dr. West cites a double-blind study showing CoQ10 to be useless in the treatment of congestive heart failure in humans. He expects CoQ10 supplements to simply die a slow death. “It will be around for years, create plenty of millionaires, and then disappear,” he predicts.

Yet other studies have shown completely different results, and many holistic veterinarians and physicians credit CoQ10 for improving their patients’ health dramatically. One explanation may be the type of CoQ10 that is used, as oil-based preparations are usually considered more effective or more easily assimilated than powders. Oil-based CoQ10 is sold in soft gel caps, while crystalline CoQ10 is sold in capsules, tablets, or powders.

Like many veterinarians, Stephen Blake, DVM, of San Diego prescribes daily doses of one milligram (mg) oil-based CoQ10 per pound of body weight for dogs with congestive heart failure and twice that amount (two mg per pound of body weight) if powdered CoQ10 is used. Similar recommendations are common for dogs with gum disease and other health problems.

The October 2001 issue of the Townsend Letter for Doctors & Patients offers additional insight. In a short article, retired chemist Wayne Martin describes his conversations with two leading CoQ10 researchers, Karl Folkers and William Judy. Martin’s friend Karl Folkers, Ph.D., who died in 1999, discovered vitamin B12 in 1948 and later worked with CoQ10 at the University of Texas at Austin and at an institute he founded. According to Martin, Professor Folkers hoped for a better way to get CoQ10 into blood circulation, as the crystalline form of CoQ10 does not pass easily through intestinal mucosa. Because CoQ10 is fat-soluble, Professor Folkers recommended taking it with a teaspoon of coconut oil.

William Judy, Ph.D., a colleague of Professor Folkers, investigated the treatment of hormone-refractory prostate cancer with CoQ10. He discovered that one way to improve the absorption of CoQ10 into the blood circulation is by melting it. Coenzyme Q10 melts at 104 degrees Fahrenheit, which is only slightly above normal body temperature. In Dr. Judy’s highly successful trial, patients taking CoQ10 consumed it in a cup of hot coffee or tea to which fat was added.

How to Give CoQ10 to Dogs

A dog’s normal body temperature (100.5 to 101.5 degrees F) is higher than the normal human temperature but still lower than the melting point of CoQ10. “If one can get a dog to drink warm water,” says Martin, “this should be a good way to give coenzyme Q10 to a dog.” Consider stirring the appropriate amount of CoQ10 into a small amount of hot water to which you have added a teaspoon of coconut oil or butter. Most dogs enjoy the taste of fats and oils, which simplifies its delivery. If necessary, the water/CoQ10/oil mixture can be poured over a favorite food.

In our follow-up interview, Martin explained that all of the world’s CoQ10 comes from a single Japanese supplier. Supplement makers may mix it with oil or put it in different types of capsules or tablets, but the main ingredient of all these products is identical.

Considering the price of CoQ10 supplements, it is reassuring to know that with the help of hot water and a small amount of saturated fat, inexpensive CoQ10 can be more easily absorbed and more thoroughly assimilated than the most expensive oil-based CoQ10 gel cap.

The post CoQ10 for Heart Health in Dogs appeared first on Whole Dog Journal.

Conventional medical practitioners consider congestive heart failure and other circulatory problems to be progressive and irreversible, but holistic veterinarians know that in many cases, heart disease can be slowed, reversed, and even cured. Understanding heart disease will help you prevent it in healthy dogs and treat it in dogs who are already ill.

UPDATE: For information on another common heart disease, dilated cardiomyopathy (DCM) in dogs, see Whole Dog Journal‘s September 2018 story.

What Does Congestive Heart Failure in Dogs Look Like?

The symptoms of congestive heart failure (CHF) are easy to overlook, and the illness is often mistaken for other conditions, such a respiratory infection or the normal aging process. In short, the condition is an inability of the heart to pump enough blood to meet the body’s needs, because of a failure to adequately empty the venous reservoirs.

In congestive heart failure, the heart doesn’t actually fail or stop beating; instead, its valves become thick with scar tissue, which prevents them from closing properly. Leaking valves cause fluid to accumulate on either side of the heart, and the heart grows larger as it works harder. Fluid accumulating on the right side of the heart produces lung congestion and coughing; fluid on the left side leads to edema (fluid retention) in the abdomen. Arrhythmia, or an uneven heartbeat, can occur as well.

In dogs as in humans, there are four functional classifications of CHF. Class 1 has no obvious signs. This early phase, during which the heart begins to malfunction, can last for years.

In Class 2 CHF, fatigue and shortness of breath begin to accompany active exercise or heavy physical activity. There are no symptoms when the dog is sitting still or lying down. A lack of circulation in the extremities in this and later stages may interfere with wound healing, and mental confusion can occasionally result from a lack of oxygen in the brain.

In Class 3 CHF, even slow walking on a level surface can produce shortness of breath and fatigue. Other possible signs include a persistent dry or hacking cough, wheezing, sudden collapse, and a bluish discoloration of the tongue and gums during exercise. Because the accumulation of fluid in the chest interferes with deep breathing, the dog may seek fresh air more than usual.

In Class 4 CHF, the patient is uncomfortable at all times, even while resting. Edema can affect the legs and feet as well as abdomen and chest area. In advanced cases, fluid collecting in the chest cavity can push on the heart and collapse the lungs. In contrast to the long time lag between Class 1 and Class 2, the illness progresses quickly from Class 3 to Class 4, so that a dog that seemed healthy and active may suddenly enter a critical condition.

Conventional vs. Complementary Approaches to Congestive Heart Failure

Conventional medicine treats CHF with diuretics, which remove accumulated fluids; digitalis or other heart drugs, which stimulate and temporarily strengthen the heart muscle; oxygen, which improves the animal’s breathing; and a low-salt diet, which helps prevent further edema. These treatments effectively treat the symptoms of the disease, vastly improving the quality of the animal’s remaining life, but do nothing to prevent the progression of the illness.

Generally, holistic practitioners also employ the effective conventional drugs to suppress the symptoms of CHF and seek to augment conventional treatments with nutritional support and herbs. Their goal is to improve whatever underlying imbalances or deficiencies the dog may be experiencing, which may help to slow or stop the progression of disease.

Since all drugs used to treat symptoms of CHF have some adverse effects, another goal of holistic practitioners is to facilitate the safe reduction or even elimination of the dog’s conventional prescriptions. Of course, success depends on the type, severity, and duration of the dog’s illness, but many veterinarians and dog guardians have seen great improvements in their patients with this approach.

Nutritional Support for Dogs with Congestive Heart Failure

Vitamins, minerals, enzymes, and other nutrients play a crucial role in maintaining circulatory health.

• Vitamins: In the 1940s, Drs. Wilfrid and Evan Shute, who were brothers, began a 40-year study of the effects of vitamin E on the heart. Wilfrid Shute’s research involved dogs as well as humans, for he was a show judge and Doberman Pinscher breeder. Soon, thanks to his efforts, vitamin E improved the health of dogs around the world.

As Wendell O. Belfield, DVM, reports in his classic book How to Have a Healthier Dog, many of these cases were dramatic. In 1945, Dr. N. H. Lambert in Dublin, Ireland, learned of the Shute brothers’ work and began giving vitamin E to dogs, the first of which, a nine-year-old Griffon, was dying of heart disease complicated by an inflammatory uterine condition. Conventional treatment had been unsuccessful. “Placed on vitamin E, she made a spectacular recovery,” Dr. Belfield reports. “Lambert said she became quite rejuvenated and lived for another six years.

“Among the virtues of vitamin E is the prevention of excessive scar tissue production,” he adds.

Vitamin C is another crucial nutrient for heart health, as it stabilizes blood vessel walls by supporting the production of collagen, elastin, and other connective tissue. Some physicians consider congestive heart failure a form of scurvy, caused by a deficiency of vitamin C. A powerful antioxidant, vitamin C protects the cardiovascular system as well as speeds wound healing throughout the body, including tiny lesions and wounds within blood vessel walls. In addition, vitamin C is a cofactor for enzymes (biological catalysts) that improve the metabolism of cholesterol and triglycerides.

But of all the vitamins associated with heart health, the most important may be those of the vitamin B complex, including one that has never been recognized as important to human health (vitamin B4, or adenine), even though animal research has shown that withholding it produces congestive heart failure. Vitamin B4 is found in yeast, liver, and wheat germ.

In the last 20 years, Bruce West, DC, has treated thousands of congestive heart failure patients with nutrition rather than drugs. Although he works with humans rather than dogs, his explanation of how congestive heart failure develops applies to both. The cause in most cases, he says, is what he calls American beriberi, or beriberi of the heart. Beriberi is a B-vitamin deficiency that causes nerve conductivity problems, weakness, and muscle paralysis. “Congestive heart failure,” he says, “is a problem of poor nerve conductivity to the heart, an almost paralyzing weakness of the heart muscle, and the resultant failure of the heart muscle to be able to pump out blood.”

Dr. West recommends nutrient-rich foods that contain the entire B-vitamin complex as well as all of the nutrients important to circulatory system health. Unlike prescription drugs, these supplements help the body repair itself by providing the nutrients whose deficiency caused the damage in the first place.

According to Dr. West, most human patients who follow his protocol reduce their prescription drugs and diuretics within a few months and stop them altogether within a year, and this is quite possible for canine patients, too. “Heart drugs are powerful and can prolong life,” he notes, “but when they are no longer needed, they can do serious damage to the heart and kidneys and should be discontinued.”

Recommended dosages vary widely, depending on the prescriber’s philosophy. Practitioners of orthomolecular medicine use very high doses of synthetic vitamins to treat heart disease and other conditions. In Keep Your Pet Healthy the Natural Way, Pat Lazarus lists the supplements used by Richard J. Kearns, DVM, to treat canine heart disease, which include 400,000 International Units (IU) of water-soluble vitamin A, 20 to 25 grams of vitamin C, and up to 4,000 to 6,000 IU of water-soluble vitamin E. Megadoses of synthetic vitamins have a drug-like effect and require professional supervision.

At the opposite end of the spectrum are those who use whole-food supplements rather than synthetic vitamins or isolated nutrients. Even though they supply individual nutrients in minute quantities, whole-food supplements such as those made by Standard Process and Wysong contain all of the C-complex, B-complex, and other families of vitamins, plus hundreds of other nutrients. Food-source supplements are readily absorbed and utilized, have no adverse side effects, and work synergistically to repair damaged tissue.

• Coenzymes: Coenzyme Q10 is used by holistic practitioners for many heart ailments, including CHF. Coenzyme Q10 (generally written as CoQ10 and pronounced “Coe-cue-ten”) is a vitamin-like substance that resembles vitamin E in its action, and strengthens the heart muscle and enhances immunity.

For his canine CHF patients, San Diego-based veterinarian Stephen Blake (see “Holistic Veterinarians Propose Other CHF Causes and Treatments” sidebar at end of story) prescribes one milligram of oil-based CoQ10 per pound of body weight per day, or two milligrams of powdered CoQ10 per pound of body weight.

• Amino acids: The amino acids taurine and L-carnitine are popular supplements because they have been shown to help strengthen the heart muscle, increase its output, and help relieve edema. These amino acids work best when given with high-quality protein and are usually recommended for CHF in doses up to 10 mg per pound of body weight.

• Minerals: Of the many minerals that help maintain heart health, the most important are found in raw bones. Dogs on a raw bone-based diet ingest these minerals daily. Calcium supports the contraction of muscle cells in the heart as well as the conduction of nerve impulses that trigger heartbeats. Magnesium helps normalize an irregular heartbeat, and works synergistically with calcium to strengthen the heart. Trace elements such as zinc, manganese, copper, selenium, chromium, molybdenum, and boron are also important, but are needed in only small quantities.

Supplements such as Calcifood, Min-Tran, and Organic Minerals from Standard Process or Wysong’s Orgamin and Chelamin contain all of these important nutrients. Powdered kelp (½ teaspoon per 15 pounds of body weight) and liquid colloidal minerals (½ teaspoon per 30 pounds of body weight) can be added to food for additional support.

• Essential fatty acids: Essential fatty acids (EFAs) can be important supplements, especially for dogs fed a grain-based commercial diet. EFA supplements that contain fish oils (marine lipids) provide omega-3 fatty acids that improve heart function by correcting EFA deficiencies and balances.

• Enzymes: Systemic oral enzyme products such as Wobenzym and Nutrizyme help repair damage to the heart and other organs, especially where inflammation is involved. Systemic oral enzymes are enteric-coated digestive enzymes taken between meals on an empty stomach.

“Instead of staying in the stomach and digesting food,” explains enzyme researcher Charles Green, “these enzymes circulate through the body, removing inflammation, breaking down scar tissue, and restoring healthy tissue.” According to Green, this therapy reduces inflammation quickly, within a matter of days or even hours, while the removal of scar tissue takes place more slowly. These products have been proven safe even in large doses for long-term use.

Herbs for Your Dog’s Heart

Of the many herbs that support heart health, several are suitable for use with dogs.

The hawthorn berry (Crataegus oxyacantha), is gentle, effective, and nontoxic. Hawthorn’s flavonoids increase coronary blood flow while slightly enhancing the force of the heartbeat; it stabilizes the pulse, increases the heart’s tolerance of oxygen deficiency, and increases cerebral blood flow. Because it has a gradual effect, hawthorn should be taken over a long period, such as several months or years, for maximum effectiveness. Prolonged use is safe, as hawthorn has shown extremely low toxicity in every animal species tested. Any hawthorn preparation sold for human use can be given to dogs, adapting label directions to the patient’s weight.

Another herb with impressive cardiovascular benefits is garlic. Garlic improves cholesterol balance, inhibits harmful platelet congregation, and acts as an antioxidant. There is much debate about which type of garlic is best, and every preparation (fresh, dried, cooked, raw, aged, or extract) has its proponents. Although side effects are rare, garlic does thin the blood and should not be used by dogs with bleeding disorders. Otherwise, it is usually safe to take in “courses” of five days on and two days off for four weeks, then discontinued for one week before resuming, with occasional breaks of a month or more.

Cayenne pepper (Capsicum annuum), another culinary herb with cardiotonic properties, helps stop internal bleeding, relieves pain, strengthens tissue, and improves circulation. Cayenne capsules are widely sold and easy to administer in food.

Other tonic herbs with circulatory system benefits include ginkgo (Ginkgo biloba), gotu kola (Centella asiatica), rosemary (Rosmarinus officinalis), and bilberry (Vaccinium myrtillus).

Liver support, which is important in most cases of congestive heart failure, is well provided by dandelion leaf or root (Taraxacum officinale) and milk thistle seed (Silybum marianum).

For best results, work with a veterinary herbalist to determine which herbs would benefit your dog, adjust the dosages, and monitor their effects. As mentioned earlier, success with nutritional support or herbal medicines may enable you to reduce your dog’s conventional medications. However, this must be done under a veterinarian’s supervision. Contact the American Holistic Veterinary Medical Association to find a holistic veterinarian in your area.

Holistic Veterinarians Propose Other CHF Causes and Treatments

It’s in the Food

To Australian veterinarian Tom Lonsdale, author of the book Raw Meaty Bones and a longtime advocate of raw diets for dogs, the cause of almost every case of canine congestive heart failure is commercial pet food. “Domestic dogs that are fed the way a wolf or dingo feeds itself bloom with health,” he says. “I’m talking about whole carcasses or large lumps of raw meat and bones as the staple of the diet. Congestive heart failure is rare in dogs that eat the diet nature intended.

“Heart disease usually starts in the mouth,” he continues. “A diet based on raw meaty bones provides the nutrients and exercise that keep teeth and gums clean and healthy, while commercial pet food promotes periodontal infections like gingivitis and pyorrhea. These infections have consequences for other body systems. Harmful bacteria drain from the mouth and spread throughout the body, leading to multiple problems, including heart disease.”

According to Dr. Lonsdale, congestive heart failure involves collagen, the connective tissue that holds the body together. Dietary deficiencies and mouth infections affect all of the body’s collagen adversely, he says. As circulatory system collagen loses its flexibility, inflammation results, producing scar tissue, leaky valves, and circulatory insufficiency.

“As with so many things,” says Dr. Lonsdale, “an ounce of prevention is worth a pound of cure. This is especially so with dogs that have an audible congenitally acquired heart murmur. If one can improve the patient’s dental hygiene and diet before signs of congestive heart failure arise, then, despite the heart murmur, general health often remains surprisingly good. That’s a relief because drug treatments are at best unreliable.”

Detoxification

San Diego veterinarian Stephen Blake agrees that congestive heart failure is a syndrome rather than an isolated illness. “It’s a mistake to focus exclusively on the heart,” he says, “because the heart is only part of the problem. Ninety percent of the congestive heart failure patients I see also have some kind of liver problem, which isn’t surprising considering our toxic environment. Dogs are exposed to toxins in their food and water, not to mention vaccines and prescription drugs, all of which overwhelm the liver. So in most cases, in addition to supporting the heart, I’m going to be treating the liver.”

Dr. Blake begins this process by removing as many toxins as possible from the dog’s environment and diet. “Anything that’s not natural should be eliminated,” he says. “I recommend that the dog not receive vaccinations, heartworm preventatives, flea or tick treatments, food that contains chemical preservatives, or anything that might contain pesticide residues or other chemicals. If the patient is on prescription medication, I consider whether going off the drug would be beneficial or dangerous. For example, if the dog has diabetes as well as congestive heart failure, I’m not going to pull him off insulin. But in most cases, you can discontinue prescription drugs by providing herbs or supplements that have similar effects.”

One patient who recovered on Dr. Blake’s protocol of improved nutrition, herbs, homeopathy, and acupuncture is Mia, a Chow who, two years ago, had a chronic lung infection and congestive heart failure. Despite conventional treatment with antibiotics, heart drugs, and diuretics, her condition was rapidly deteriorating.

“She was on a low-protein food for senior dogs,” he says, “and that has to be the worst kind of diet for the heart. We increased the amount of protein in her diet and improved its quality by switching her to raw meat and bones. I had her take colostrum, which is rich in growth factors and helps promote tissue repair, as well as Cardio-Plus and glandular products from Standard Process for support of the heart. Then I chose a homeopathic remedy to fit her constitutionally.

“At her first appointment, this dog could barely breathe, coughed all the time, was extremely uncomfortable, and was close to death. Now she no longer takes Lasix (her prescription diuretic) or other medications except for one heart drug, which she takes at a reduced dose. She just turned 16 and is in great shape, full of spit and vinegar.”

Homeopathy and Energy Medicine

Gloria Dodd, DVM, uses homeopathy, nutrition, and energy medicine to treat dogs with CHF. Her Web site features beforeand-after photos of some of her patients, including Snookie, a 12-year-old spayed female Poodle who had severe congestive heart failure, emphysema, plus liver and digestive problems. She was also deaf.

After treatment with an improved diet and Dr. Dodd’s homeopathic combination for CHF, Snookie looks years younger. Her lungs are clear, she plays like a puppy, and her hearing has returned.

Dr. Dodd’s interest in energy medicine prompted her to design a halter that combines color therapy, quartz crystals, pyramid configuration energy, heart chakra energy, and an antiradiation bead. The first dog to wear the harness, which now comes in different sizes, was her own Poodle, who had CHF and a severe mitral heart valve murmur. After wearing the halter, her CHF and heart murmur disappeared. Now 18 years old, the Poodle has remained active and free from disease for the past four years, with all clinical exams and blood tests remaining normal.

“The basis of all my treatment for any illness is one of detoxification and support, which I describe on my Web site,” says Dr. Dodd. “I find that in order to effect a cure (and that is what I aim for; I don’t espouse repressive therapy even with natural methods), one has to ferret out the true cause of disease. It is multilayered, and I consider energy medicine my most important tool.”

Unorthodox Approaches

As one might guess, the ideas forwarded by these holistic practitioners are not supported by most conventional practitioners, who generally treat CHF with modern pharmacology alone. If your conventionally oriented veterinarian scoffs at your queries regarding complementary therapies, look for a holistic veterinarian who can augment your healthcare options. The American Holistic Veterinary Medical Association (AHVMA) can help you find a practitioner in your area.

In Conclusion

Congestive heart failure has many possible causes and many possible treatments. By focusing on diet and nutrition, by avoiding conditions and products that add stress to the body, and by providing appropriate support therapies, many patients with CHF can experience a total restoration of health.
