- The FDA is investigating a potential link between pet diets and dilated cardiomyopathy, a disease that weakens the heart in dogs and can lead to cardiac failure.
- The agency named 16 brands most frequently involved in the reports.
- The agency first started investigating the possible link after receiving reports of the disease in breeds that were not commonly associated with DCM.
The Food and Drug Administration is investigating a potential link between certain brands of dog food, including Blue Buffalo, Merrick and Rachel Ray Nutrish, and an increased risk of heart disease in pets.
The agency is looking into more than 500 cases of canine heart disease, identifying the brands of dog food that have been most frequently fed to pets with the disease.
Consumers were first warned last year by the FDA that there is a potential link between particular pet diets and dilated cardiomyopathy, or DCM — which can weaken a dog’s heart and lead to cardiac failure — after the agency started receiving reports of the disease in breeds that were not commonly associated with DCM.
