Some general types of heart disease include:

Types of Heart Disease: Dilated Cardiomyopathy

Dilated Cardiomyopathy is the degeneration of the heart muscle. This is the most common cause of heart failure in large breed dogs. Although normally found in large breeds, it has been recognized in other breeds such as American and English Cocker Spaniels, Bull Terriers, and English Bull Dogs. Early signs of the disease can include anorexia, weakness, coughing, and exercise intolerance that commonly progress to congestive heart failure.

Degenerative valvular disease, particularly of the mitral valve, is the most common canine cardiovascular disease. This disease is primarily seen in older, small breed dogs. Approximately 30-35% of dogs older than 13 years of age will exhibit murmurs. Coughing is a common symptom; other signs include an irregular breathing pattern, exercise intolerance, fainting, and abdominal distention.
