At this time, White Rock Veterinary Hospital recommends that you do NOT feed your pet a grain-free diet until more research is done.

In June 2019, the US FDA publicly identified the pet food brands most frequently associated with cases of dilated cardiomyopathy (DCM), a serious and potentially fatal heart disease. The agency has been investigating the problem since last year.

90% of the foods implicated are labeled as “grain-free” meaning that they do not contain corn, soy, wheat, rice, barley, or other grains. 93% of the diets contain, as the main ingredients, peas, lentils, other legume seeds (known as pulses), and/or potatoes. The cause of the problem is unknown and the FDA cannot say with certainty that diet is the culprit. The potential association between diet and DCM in dogs is a complex issue that may involve multiple factors

DCM is a condition resulting in an enlarged, weak heart that cannot pump blood efficiently. Dogs with DCM may tire easily, cough, and have trouble breathing. More dramatically, they might exhibit sudden weakness, collapse, faint, or die without warning. Particular dog breeds are known to be genetically predisposed to DCM, including Dobermans, Great Danes, Newfoundlands, Boxers, Irish Wolfhounds, and Cocker Spaniels. Many of the dogs affected are not of these breeds.

There has been no research to show that grain-free is a superior or healthier diet for dogs. The grains in pet foods provide nutrients and are not just fillers. The starches in grains are highly digestible. Also, true food allergies are rare and protein sources are much more common offenders than the carbohydrate source.
