The UC Davis Cardiology Service has developed this document in response to the alerts from the FDA. These alerts identify an associated risk for some grain-free diets containing certain ingredients (legumes like peas, pea components, lentils; white potatoes, sweet potatoes) and a diagnosis of dilated cardiomyopathy (DCM).

What is Dilated Cardiomyopathy (DCM)?
DCM is a heart muscle disorder that results in a weak pump function and heart chamber enlargement. In the early stages of this disease pets may appear totally healthy with no apparent clinical signs. Later in the course of this disease, dogs may have a heart murmur, an arrhythmia (irregular heart beat), collapse episodes, weakness or tiredness with exercise, and even trouble breathing from congestive heart failure. While there are some breeds of dogs (like Dobermans) that have a genetic predisposition to development of DCM, there are also nutritional factors that may result in this disease.
What should I do?
If you are feeding a diet of concern based upon the FDA alert we recommend that you consult with us or a veterinary cardiologist. UC Davis provides 4 general points for guidance below:

*Please note with recent increase in the number of dogs screened for taurine deficiency, we are seeing dogs with values within the reference ranges (or above the “no known risk for deficiency range”) yet are still exhibiting signs of cardiac disease.
