Dilated cardiomyopathy occurs when the heart chambers become enlarged and the walls of the ventricles become thin. Thia causes the heart muscle to weaken and eventually fail. It’s the most common reason for congestive heart failure in large and giant- size dogs, and it primarily affects male dogs. Some of the breeds that are prone to dilated cardiomyopathy include Boxers, Doberman Pinschers, Springer Spaniels, and Cocker Spaniels. Signs of the disease usually appear when the dog is between two and five years of age. They include rapid weight loss, lack of energy, rapid breathing, and frequent coughing, sometimes bringing up blood. The condition is diagnosed through electrocardiograph, chest x ray, and echocardiogram.
