The Food and Drug Administration has issued a warning of a possible link between certain types of dog food and a canine heart disease called canine dilated cardiomyopathy, or DCM. It is an updated study from a previous investigation where some brand dry dog food including ingredients including peas, lentils, potatoes, and sweet potatoes have caused DCM. It's important to note that it was primary effecting large dogs.

Breeds that are typically affected are large and giant breed dogs, according to the FDA. However, many of the 524 cases of DCM reported to the FDA have included smaller breeds of dogs, suggesting a lack of a genetic connection", according to WHDH.
