Heart disease is commonly associated with humans, but did you know it affects our dogs too? In fact, nearly eight million dogs in the US have heart disease – that’s one out of every ten canines. Recent research shows that up to 75% of dogs aged seven and older will develop some form of heart disease. These statistics are alarming, but there is hope. Advances in veterinary medicine and laboratory testing are helping veterinarians detect heart disease earlier. We have also gained valuable insights into the relationship between a dog’s genetics, lifestyle, exercise levels, diet, and the risk for heart disease. In addition, specific foods, supplements, and lifestyle changes can help lower your dog’s heart disease risk.
Common Forms of Heart Disease in Dogs
Heart disease in dogs can be congenital or acquired. Congenital heart disease has a genetic link and is present from birth, while acquired heart disease occurs with age due to diet and/or disease. The two most common forms of heart disease in dogs are dilated cardiomyopathy (DCM) and mitral valve insufficiency (MVI).
1. Dilated cardiomyopathy
In DCM, the cardiac muscle surrounding the heart becomes thin and weak, impairing proper contraction and circulation. Symptoms may include a heart murmur, coughing, difficulty breathing, weight loss, and fainting. DCM may be genetic or acquired and is especially common in large breeds like Great Danes, Dobermans, and boxers.
2. Mitral valve insufficiency
MVI is the most common heart issue in dogs, with nearly 90% of dogs over age 13 developing some form of this disease. In MVI, the fibers of the mitral valve thicken and degenerate, impairing blood flow and circulation. MVI usually occurs in small to mid-sized breeds like miniature and toy poodles, Dachshunds, Chihuahuas, Maltese, and Cavalier King Charles spaniels. Signs may include a heart murmur, fatigue, coughing, difficulty breathing, weakness, and loss of appetite.
Signs of Canine Heart Disease
If you notice any of the following signs in your dog, it’s important to take her to the vet for a checkup:
- Coughing for three or more days, especially in the morning
- Difficulty breathing, panting excessively, or increased respiratory rate
- Changes in your dog’s behavior, such as being more withdrawn, tired, or depressed
- Poor appetite and weight loss
Routine diagnostics for heart disease include blood and urine tests, chest X-rays, and an electrocardiograph (EKG) to detect electrical disturbances in the heart. Definitive diagnosis is confirmed with an echocardiogram, which helps pinpoint the specific problem within the heart.
Canine Heart-Healthy Foods
To support your dog’s heart health, feed him an organic, fresh, vegetable-rich food that includes the following:
- High-quality lean protein: Chicken, turkey, pork, and fish are excellent sources of lean protein that strengthen the heart muscle.
- Low sodium levels: Excess salt is never beneficial, especially for dogs at risk of cardiac issues. Keep your dog on a diet that provides less than 100 mg of sodium daily.
Nutritional Supplements that Support Heart Health in Dogs
A wide range of supplements can help support your dog’s heart health. Consider incorporating the following into your dog’s diet:
- Omega-3 fatty acids: These reduce inflammation and protect against abnormal heart rhythms. Natural sources include cod liver oil, sardines, and salmon, or you can use supplements.
- CoQ10: This coenzyme helps protect your dog’s heart muscle and is available in supplement form. Consult with your vet for the appropriate dosage.
- Taurine: Supplementing your dog’s diet with taurine helps maintain normal cardiac function. Cooked lamb, raw beef liver, and taurine supplements are good sources.
- Antioxidant vitamins: Vitamins A, C, E, and B-complex, as well as magnesium, are beneficial for heart health.
Manage Your Dog’s Weight
Keeping your dog at a healthy weight is crucial for good overall health and especially important for dogs with heart issues. Practice portion control and feed your dog two to three balanced meals each day. Regular exercise, such as walking or swimming, also decreases the risk of canine heart disease.
Pacemaker Surgery for Dogs
Pacemaker surgery is an effective treatment for electrical disturbances in the heart that are unresponsive to medication. During the surgery, a pacemaker is inserted through the jugular vein and placed in the heart. The pacemaker’s generator, located in the dog’s neck, ensures proper heart rhythm.
Homeopathic Remedies for Canine Heart Disease
When using homeopathy, consult with a veterinarian experienced in this modality. Some remedies that may be helpful include:
- Crataegus oxycantha 3x (Hawthorn berry) for heart weakness and murmurs.
- Digitalis purpurea 6x (foxglove) for irregular heartbeat.
While receiving a diagnosis of heart disease for your beloved dog is never easy, there are ways to support their cardiac health and improve their quality of life. Early diagnosis is key, so if you notice any signs or symptoms, take your dog to your integrative or holistic vet as soon as possible. Together with your vet, you can develop a treatment plan that includes dietary and lifestyle changes, along with any necessary supplements or medications.
