Grain-free diets for dogs are becoming increasingly popular, but concerns are emerging following the FDA's recent investigation that there might be a link between grain-free diets and Dilated Cardiomyopathy (DCM) in dogs with no known genetic predisposition. Contrary to the majority of the public thought, dogs do nutritionally require grains, and there is rarely a medical reason to switch to a grain-free diet. Not all cases of DCM are linked to diet, and many dogs who are fed grain-free diets do not develop the disease; the extent of this issue therefore is not entirely known. This review aims to explore what is known about DCM and grain-free diets and discuss the issues in researching this potential tie. DCM is linked to grain-free diets mainly through inadequately low taurine levels, due to the grain-free substitutes that have skewed macro nutritional ratios and poor bioavailability.
