Study Finds Spike in Deadly Heart Disease Linked To Trendy Dog Diets

University of California, Davis, veterinarians led a team that has found a link between some popular grain-free, legume-rich dog diets and a type of nutritional deficiency and canine heart disease known as taurine-deficient dilated cardiomyopathy.
