Dilated cardiomyopathy is a disease of the heart muscle that results in an enlarged, weakened and flabby heart that is unable to pump blood effectively. This results in blood backing up into the lungs or abdomen.

Early signs are a decrease in ability or willingness to excercise. Later signs may include abdominal distension, variable appetite, weight loss, coughing, fast or difficult breathing and possibly episodes of collapse or fainting. In an extreme case, sudden death may occur.

Early detection can help save your pet. If your pet shows any of these signs, contact your veterinarian.
