Dog Heart Disease
There's no single cause of heart disease in dogs. Aging, obesity, breed, and nutrition can all play a role. Heart valve problems are the most common issue and typically affect small breed dogs that are five years or older.
No matter what heart condition your dog has, it's important to spot the signs early. Since 95% of heart conditions in dogs come on as they age, it's easier to manage as soon as it develops.
Two Main Heart Conditions in Dogs
At CVCA Cardiac Care for Pets, we see a lot of different heart conditions in dogs, but the following are the two most common.
Valve Disease: This is due to thickened heart valves that begin to leak causing back and forth blood flow within the heart. The heart enlarges and the amount of blood that can be pumped to the body goes down. Valve disease is a heart condition more common in smaller dogs.
Heart Muscle Disease: This is a condition that weakens the heart and also lowers the amount of blood that can be pumped to the body. This is more common in larger dogs.
