There are no recalls yet, she said. The FDA began investigating this matter after it received reports of DCM in dogs that had been eating these diets for a period of months to years. They can develop congestive heart failure, which can be fatal. A far smaller proportion contained potatoes. It can take multiple months to see improvement in many cases of diet-related DCM. The common factor was a diet heavy in peas, lentils, chickpeas and potatoes — carbohydrates typically intended to replace grains. The FDA isn’t suggesting that pet owners stop feeding their dogs the particular brands yet, but some vets are already advising against “grain free” foods.

Vet-LIRN is currently evaluating the heart histopathology for two of the deceased dogs. Rosenthal and Dr.
Rosenthal feeds his own American bulldog, Eddie, a diet from a mainstream commercial pet food maker that includes grains. Genetic forms of DCM tend to affect male large and giant breed dogs beginning in middle to older age. For more information about heart disease in dogs, please see our HeartSmart website. The foods of concern are those containing legumes such as peas or lentils, other legume seeds, or potatoes listed as primary ingredients. Millions of dogs happily and safely vacuum up these diets. Many of these case reports included breeds of dogs not previously known to have a genetic predisposition to the disease. It is also seen in Cocker Spaniels associated with taurine deficiency. When supplemented with high doses of taurine, these dogs resolved their cardiomyopathy in many cases. If the diet is boutique, contains exotic ingredients, or is grain free, you may consider a diet change to one without these properties. Currently, none of the limited-ingredient diets manufactured by the major pet food manufacturers — Hills, Purina, Royal Canin — have been associated with current cases of diet-associated cardiomyopathy.
This is a very specific type of heart disease where the heart muscle stretches, gets thinner and cannot properly contract. Cats fed taurine-free diets were unknowingly given cardiac complications. Taurine is plentiful in most animal tissues, so feral and wild cats that hunt for their food derive adequate taurine from their diet. But 30 years ago, not all commercial cat foods contained sufficient amounts of taurine, leading some cats to develop dilated cardiomyopathy and other health issues. This discovery resulted in pet food companies adding more taurine to the foods they manufacture. Subsequently, taurine-associated dilated cardiomyopathy in cats has become a thing of the past.
