FDA Continues to Investigate Link Between Grain-Free Foods and Canine Heart Disease

The Food and Drug Administration announced it will continue to investigate the link between “grain-free” dog foods and canine heart disease.

The most current report is the third one, following an update in February 2019. The FDA is investigating cases of canine dilated cardiomyopathy, or DCM, in dogs eating pet foods labeled as “grain-free” that contain high concentrations of peas, lentils, and potatoes.

The report says the recent spike in DCM cases occurred in the last few years so the FDA is working with the pet food industry to look at whether changes in ingredients, ingredient sourcing, processing or formulation may have contributed to the DCM cases.
