500 cases of dilated cardiomyopathy in dogs have been connected to popular dog food brands.

The last thing any dog owner wants to do is worry that what is nourishing their pooch could also be hurting them. The Food & Drug Administration has released a list of dog food brands (below) that are connected to causing dilated cardiomyopathy, a disease of the heart muscle that causes weakened contractions and reduced pumping of blood. Over time, this disease progresses to congestive heart failure.

Many of the tested dog foods were labeled as “grain-free” and contained ingredients such as peas, lentils, other legume seeds, or potatoes and a majority of the dogs in the investigation did not have a genetic predisposition to dilated cardiomyopathy.
