The US Food and Drug Administration is investigating a possible link between incidents of canine cardiomyopathy (DCM) in dogs and extended consumption of "Grain Free" dog food after several reports from veterinarians.

The condition is one of the most common causes of heart failure in a certain large breed, such as Dobermans, boxers, but reports from the FDA show DCM occurring in breeds not usually prone to the disease, such as Retrievers, Whippets, even some mixed breeds.

The one common factor in the reported cases seems to be a diet high in things like potatoes, peas, lentils, legume seeds, which are often the man ingredients in dog food labeled as "Grain Free".

No specific brands of dog food were mentioned in the FDA warning, but owners can check to see if potatoes, peas, lentils or legumes are listed as main ingredients in their pet's food. Even better check with your veterinarian for recommendations about their best diet for your own furry friend.
