Dilated Cardiomyopathy is a heart disease that results in weakened contractions and poor pumping ability. As the disease progresses the heart chambers become enlarged, one or more valves may leak, and signs of congestive heart failure develop. The cause of dilated cardiomyopathy is unclear in most cases, but certain breeds appear to have an inherited predisposition.


It is most commonly treated with medication although surgery may be necessary for serious cases.

Cost to Treat: Heart surgery to correct dilated cardiomyopathy will cost $10,000 to $20,000 depending on your dogs breed and the severity of the problem.
