Cardiomyopathy is a disease of the heart muscle. It can affect both dogs and cats, but it occurs most often in older animals.
Cardiomyopathy causes the heart muscle to become enlarged and stiff, making it difficult for the heart to pump blood efficiently throughout the body. This can cause fluid retention, irregular heartbeat and breathing problems.
There are many types of cardiomyopathy, each with its own signs and symptoms. Some types of cardiomyopathy are more common in dogs than in cats, while other types are more common in cats than in dogs.
Signs & Symptoms of Cardiomyopathy in Dogs
The signs and symptoms of cardiomyopathy depend on which type is present and how much damage has been done to the heart muscle by this disease. They include:
- Heart failure (panting, increased thirst and urination)
- Fluid retention (swelling around eyes or abdomen)
- Weakness or collapse
