On July 12, the U.S. Food & Drug Administration (FDA) issued a brief stating they are investigating recent case reports of a type of canine heart disease known as dilated cardiomyopathy, or DCM, in dogs not genetically predisposed to the disease who may have been fed certain types of diets. Members of the Pet Food Institute (PFI) are committed to the production of safe, nutritionally balanced pet food and are working closely with FDA and internal experts to advance the understanding of this potential issue. Below, we provide answers to some questions that pet lovers may have about DCM and their dog’s diet.

What is dilated cardiomyopathy (DCM)?
DCM is a specific type of heart disease which, in dogs, results in an enlarged heart. Some dog breeds are genetically prone to this disease, such as the Doberman Pinscher, the Great Dane, the Boxer, and the Cocker Spaniel. Symptoms of DCM include a decreased appetite, lethargy and coughing.

FDA’s investigation is specifically focusing on DCM and not canine heart disease as a whole. If you have questions about DCM or your pet’s health, consult with a trusted veterinarian.

What role does diet play in DCM?
The exact cause of recent reported incidents of DCM has not yet been identified. One avenue the FDA is investigating is a possible role of specific ingredients that may be found in certain dog food recipes.
Is grain-free pet food safe for my pet?
Millions of dogs are thriving on grain-free dog food every day. In comparison, FDA has received to date a relatively small number of valid reports indicating that certain grain-free diets may possibly have played a role in DCM. FDA’s investigation includes certain ingredients that can be used in greater proportions in some pet food products labeled as grain-free.

The exact cause of these cases of DCM is still unknown and may be the result of many factors. If you have a question about your dog’s food, we recommend that you contact the manufacturer to learn more.

Should I avoid certain ingredients or grain-free dog food as a whole?
The FDA stated on Aug. 10 that “we are not advising dietary changes based solely on the information we have gathered so far” and listed “legumes like peas or lentils, other legume seeds, or potatoes” as under consideration. The agency also noted that the investigation is in its early stages. It is too early to establish any linkage to any specific ingredient.

Why may pet food makers use certain ingredients in dog food?
Pet food recipes that are formulated to provide complete and balanced nutrition offer the essential nutrients that a pet requires for his or her specific life stage, and at the proper levels. The ingredients used in pet food will help to deliver those nutrients and some ingredients may help deliver multiple nutrients. When developing a recipe, pet food makers consider factors, such as an ingredient’s nutrient profile, its role in helping the food hold shape, flavor, digestibility and shopper preference.
Should I be concerned if my pet’s food contains one of the ingredients mentioned by the FDA?
It is important to make sure the food you are feeding your pet is formulated to be complete and balanced for a pet’s life stage. If you have additional questions related to a specific ingredient we suggest reaching out to the pet food manufacturer. For concerns about your pet’s health, we recommend reaching out to your veterinarian.
Are pet food ingredients safe?
As makers of the sole source of nutrition for America’s pets, PFI members hold pet food safety as the number one priority. U.S. pet food makers use ingredients that have been accepted by the FDA, meet the agency’s requirements under Generally Recognized as Safe (GRAS), or have been adopted by the Association of American Feed Officials (AAFCO).
