Cooperation between veterinary cardiologists, nutritionists, and the USFDA has confirmed that the increase in canine and feline DCM is linked to grain-free diets. The dogs and cats affected are often being fed boutique diets that contain exotic meats and are grain-free.
Is DCM linked to grain free diets?
FDA has received reports of non-hereditary DCM associated with both grain-free and grain-containing diets. Most of the diets associated with reports of non-hereditary DCM have non-soy legumes and pulses (e.g., peas, lentils, etc.) high in their ingredient lists.
Does grain free food cause problems in cats?
