While some dog breeds are more prone to heart disease, it is a condition that can, unfortunately, affect any dog. Several different heart diseases can affect dogs, and it’s a good idea to get to know the symptoms and causes of these diseases so you can treat them as early as possible.
Around 10% of all dogs in the United States, almost 8 million, suffer from heart disease. While there are various causes of heart disease, including breed genetics, obesity, and nutrition, old age is the most common time for dogs to develop heart problems. The older your dog is, the higher the risk, and up to 75% of senior dogs have a heart condition of some kind. Unfortunately, a large percentage of these diseases go undetected and can quickly develop into a serious problem.
In this article, we look at the cause, symptoms, and treatment of heart disease in dogs, as well as the different types of heart issues that they can suffer from.
Common types of heart disease in dogs
One of the most common types of heart disease in dogs, chronic valvular disease reduces the amount of blood that can be pumped around the body. The valves that act like doors between the valves of the heart stop working properly, usually by leaking, and reduce the pressure needed to effectively pump blood.
Myocardial disease is the weakening or inflammation of heart muscles, which can cause the improper function of the heart, resulting in the heart pumping inefficiently.
Dilated Cardiomyopathy (DCM)
DCM is a disease of the heart that results in its decreased ability to generate enough pressure to effectively pump blood around the dog’s vascular system.
Some dogs inherit congenital abnormalities at birth, usually but not always due to breed-specific issues. The most common of these heart diseases include patent ductus arteriosus, pulmonic and aortic stenosis, persistent right aortic arch, and ventricular septal defect.
Symptoms of heart disease in dogs
There are several other, less common heart problems that dogs can suffer from. However, no matter the specific illness, most of them share common symptoms that can alert you that there’s an issue at hand. Symptoms include:
Causes of heart disease in dogs
While there is usually no single cause of heart disease, nutrition and age have arguably the biggest roles to play. Senior dogs are most likely to develop heart disease, but this may be related to lifelong nutrition and exercise than just old age itself. Common causes of heart disease include:
This is why reputable breeders always screen purebred dogs that they intend to breed, to try to pick up any heart defects before they are passed on. This, combined with a healthy diet and regular exercise, will go a long way in the prevention of heart disease.
Diagnosis and treatment of heart disease in dogs
If you’ve noticed any symptoms in your dog, it’s important to take them for a checkup with the vet as soon as you can. Your vet will perform several diagnostic tests to determine whether there is an issue with the heart, including:
While heart disease is a serious matter, in most cases, it is treatable, especially in younger dogs. Heartworm can be successfully treated with potent medication, and other issues may simply require an alteration of diet, increased or decreased exercise, and consistent monitoring. For more serious conditions, surgery may be required, but this is not as common as you’d imagine.
While most treatment options will not reverse heart disease, with careful management most dogs can live a relatively normal life. Your vet will help you take the steps to properly manage the disease, but good nutrition will be of the utmost importance.
