Potato-Based Pet Food Could Be Linked to Heart Disease in Dogs

If you have a pup at home, you may want to check the ingredients listed on that bag of dog food in your cupboard. The U.S. Food & Drug Administration has warned that potato-based pet foods might be linked to heart disease in dogs, Time reports.

Foods containing lentils, peas, and other legume seeds are also a potential risk, the agency’s Center for Veterinary Medicine announced.

“We are concerned about reports of canine heart disease, known as dilated cardiomyopathy (DCM), in dogs that ate certain pet foods containing peas, lentils, other legumes or potatoes as their main ingredients,” Martine Hartogensis of the veterinary center said in a statement. “These reports are highly unusual as they are occurring in breeds not typically genetically prone to the disease.”

Recent cases of heart disease have been reported in various breeds—including golden and Labrador retrievers, miniature schnauzers, a whippet, a shih tzu, and a bulldog—and it was determined that all of the dogs had eaten food containing potatoes, peas, or lentils.

While heart disease is common in large dogs like Great Danes and Saint Bernards, it’s less common in small and medium-sized breeds (with the exception of cocker spaniels). If caught early enough, a dog’s heart function may improve with veterinary treatment and dietary changes, the FDA notes. While the department is still investigating the potential link, it’s best to err on the side of caution and avoid foods containing these ingredients until further notice.

As shown by the recent romaine lettuce scare linked to E. coli, the FDA is unable to request a food recall unless a specific manufacturer or supplier can be identified as the source of contamination. Instead, public notices are generally issued to warn consumers about a certain food while the agency continues its probe.
