Overview
Dilated Cardiomyopathy (DCM) is a serious heart condition characterized by the enlargement of the heart chambers and weakened heart muscles, leading to reduced cardiac output. It primarily affects dogs, but can also occur in cats.
Causes
DCM can be caused by genetic factors, nutritional deficiencies (such as taurine deficiency in cats), or infections. Certain breeds are more predisposed due to genetic factors.
