There are two types of cardiac failure or myopathy that occur in dogs. In one form called hypertrophic cardiomyopathy the walls of the chambers of the heart thicken, leading to a decrease in pumping efficiency. This form of cardiac failure is quite rare in dogs. In the second form of cardiomyopathy the chambers of the heart increase in size and the muscles that form the walls of the heart stretch thinner. This is called dilated cardiomyopathy. This is the type that leads to congestive heart failure (CHF) in our pets. Canine Dilative Cardiomyopathy is one of the causes of CHF.
For reasons we do not understand, the incidence of cardiomyopathy in doberman pinchers is greater than that in all other breeds combined.Doberman pinchers develop abnormal electrocardiograms up to four years before they develop clinical signs of heart failure. Many of these dogs die suddenly without warning. Owners often think these dogs have been poisoned. Others develop the cough and fluid retention characteristic of the heart failure along with muscle wasting and difficulty getting about.By the time dogs become symptomatic with cardiomyopathy and congestive heart failure, they rarely live beyond a year. Many will die in six months. The disease is known to run in families so families with this problem should not be bred.
Nothing you did caused this problem. The disease runs in blood lines so it was probably preordained that your pet was susceptible to the disease.I am sorry again for your loss . Take care
