Causes, Signs, And Treatments For Canine Heart Disease

A healthy heart is imperative for your dog to grow, live, and thrive. Unfortunately, an estimated 10 percent of all dogs have heart disease. Even though it is common, most people do not really understand heart disease or its dangers.
With this guide and your veterinarian's help, you will learn the causes, signs, and treatment options for canine heart disease.

Causes
Unfortunately, there is no single cause of heart disease. In fact, there are a variety of issues that can increase your dog's risk of developing heart disease. There are also different types of heart disease, which are caused by different factors. Unlike the heart disease that affects humans, tobacco products or fatty diets will not cause your dog's heart disease. Age, however, is a factor, so the older your dog is, the more risk they have of developing heart disease. Valvular disease is the most common form of heart disease in dogs. This form of heart disease is characterized by a breakdown and thickening of the heart valves. It mostly affects smaller dog breeds who are 5 years of age and older. Heartworm disease is another common cause of heart disease in dogs. As the name suggests, this form of heart disease is caused by heartworms, which can be prevented with proper medication. Myocardial is another form of heart disease that usually affects large breed dogs. This form of heart disease affects the systolic function of the heart.

Signs Every dog is different, but there are a few signs to watch for if you are concerned about heart disease in your dog. Coughing is one common sign of heart disease. If your dog's coughing seems to be constant and lasts for more than 3 days, schedule a full medical evaluation. Dogs with heart disease will also have breathing issues because fluid builds up around the heart and lungs. You may notice your dog pants continuously even when they are not hot or tired or your dog may struggle to calm themselves, breathing heavily and haphazardly when they overexert themselves. Dogs with heart disease may also have shallow, labored breathing or take rapid, deep breaths. Shortness of breath or difficulty breathing can also lead to your dog passing out. Weakness and fatigue are also common with dogs who have heart disease. You may notice your dog no longer wants to run and play or is unable to walk up the stairs or jump on furniture. Your dog may also sleep more than usual. Even though they may feel fatigued, dogs with heart disease may also become restless at night. Again, this stems from the fluid that builds up around the heart and lungs, which makes your dog uncomfortable and agitated. If you notice swelling around your dog's stomach and different extremities, they may have edema, which is another sign of heart disease that occurs when the blood flow is interrupted or slowed.

Treatment
If you suspect your dog has heart disease, talk to your veterinarian. Early intervention can mean the difference between life and death. And the right treatment will depend on the cause of your dog's heart disease. For example, if your dog's heart disease stems from valve issues, surgery may be recommended. While invasive, surgery to repair the valves can restore the cardiovascular system to a fully-functional state.

Pacemakers may also be options recommended by your dog's veterinarian to improve the heart's function.
For dogs with heartworms, injectable medications are used to kill the heartworms.
Also, veterinarians may suggest a diet low in salt/sodium. This will help your dog's body retain less fluid, which reduces the pressure and stress placed on the heart and lungs.
