The U.S. Food and Drug Administration (FDA) concluded that there is no scientific evidence that a grain-free diet causes canine dilated cardiomyopathy (DCM). 

The agency outlined the multiple potential factors that can, alone or in combination, contribute to dogs developing this rare and scientifically complex disease. The agency concluded that there is nothing inherently unsafe about a grain-free diet. 

Dr. Steven Solomon, director of the FDA’s Center for Veterinary Medicine, acknowledged that the “complex scientific messaging” on DCM and diet has contributed to misinterpretation about the safety of a grain-free diet. Dr. Solomon encouraged dog owners to select the diet that works best for their pet’s nutritional needs and previewed more multidisciplinary, scientific collaboration between the industry, veterinarians, scientists and other researchers that will further the understanding of DCM.
