New studies say grain free dog food has been linked to heart failure in dogs. An FDA investigation sparked in light of these findings.

Grain free dog food has become a popular trend for pet owners. But new research says it might not be as healthy as some originally thought

Grain Free food contains peas, lentils, legume seeds or potatoes, instead of typical grain and corn.
Professionals say that they have seen a rise in canine dilated cardiomyopathy, which is just another name for a dog heart disease, in dogs eating this type of food.

Symptoms include fatigue, coughing and trouble breathing in dogs.

Associate Veterinarian at Missouri Valley Vet, Dr. Crystal Reed says, “The good news it does seem to be reversible, you add torres into the food and it reverses. They haven’t been able to link specific grain free foods to the dilated cardiomyopathy so its still in the early stages at this point.”

The FDA has not correlated any specific brands yet or told people what exactly to do.
Large breed dogs, such as Great Danes, Boxers, Saint Bernards are more frequently affected by heart disease as well.
