(CNN) – The Food and Drug Administration wants pet owners to be aware of what’s in their dog’s food and how it could impact their pet’s health.
It’s continuing to investigate a connection to certain dog food ingredients and canine heart disease.
Many of these foods are labeled as “Grain-free,” with main ingredients like peas, lentils and potatoes.
The investigation started in July 2018.
This week, the FDA released its third report in the investigation, which includes 16 pet food brands linked to more than 500 cases of canine heart disease.
Those brands include Blue Buffalo, Natural Balance, Nutro and Rachel Ray Nutrish.
The f-d-a is asking pet owners and veterinarians to report any cases of canine heart disease.
