Dilative Cardiomyopathy in Dogs ------------------------------- General Information Dilative cardiomyopathy generally affects large breeds of dogs, usually 3 years of age and older. The disease is due to weakness of the heart muscle, which causes the heart to enlarge (dilate) and pump inefficiently. Dilative cardiomyopathy probably results from severe muscle damage caused by infection or some other mechanism. Occasionally dilative cardiomyopathy is associated with other diseases, especially the gastric dilation/torsion syndrome. The end result of the disease is heart failure. Important Points in Treatment 1. Dilative cardiomyopathy is a very serious condition. Most dogs only live for a few months after diagnosis. 2. Giving all the medication on schedule is extremely important. Please call the doctor if you cannot medicate your pet as instructed. 3. Activity: Your pet's activity must be severely restricted.
