Feeding Grain-Free? Your Dog may be at Risk for Heart Disease

In veterinary medicine, we have the ability to treat a myriad of conditions—from sensitive stomachs to skin issues and everything in between—with the help of balanced, therapeutic diets. But what happens when what we feed actually causes health problems for our pets? An alarming trend is causing veterinary professionals to take a closer look at the link between popular pet diets and heart disease.

Diet and dilated cardiomyopathy: What’s the connection?

In July, the U.S. Food and Drug Administration (FDA) issued an alert about increased reports of dilated cardiomyopathy (DCM) in dogs eating diets containing peas, lentils, other legume seeds, or potatoes as main ingredients. These ingredients are commonly found in boutique (small manufacturer) grain-free or exotic-ingredient diets, which use non-traditional protein sources.

DCM is a disease that weakens and enlarges the heart muscle, reducing its ability to pump blood efficiently. Over time, changes in the heart’s structure and its decreased function often result in congestive heart failure and can even cause sudden death.

Grain-Free foods may increase the risk for dilated cardiomyopathy

Among the dogs affected, many were found to have low levels of taurine, an amino acid that ensures the proper function of minerals and supports cardiac function. While taurine deficiency has been associated with the development of DCM, it does not appear to be the cause of all diet-related DCM cases. Fortunately, unlike genetic forms of DCM, diet-related DCM is reversible with treatment. At this time, no cases have been reported in cats.
