DCM is a disease of the heart muscle itself where the dog’s heart fails to pump effectively. The contractions of the heart are weak and therefore blood is not moved forward through the vascular system efficiently.
Typically, the heart stretches and enlarges, which over time further decreases its ability to pump and maintain healthy blood flow.
DCM is the second most common form of heart disease in a dog.
DCM usually occurs in medium- to large-breed dogs such as Dobermans, Boxers, Great Danes, Dalmatians, Irish Wolfhounds, St. Bernards, English Bulldogs, and Cocker Spaniels.
