After investigating since July 2018 the Food and Drug Administration identified 16 brands of dog food that had been linked to heart disease in dogs that eat them.
Most cases of Canine DCM (a disease of a dog’s heart muscle, can often result in congestive heart failure) were in large dog breeds, such as golden retrievers, Labrador retrievers, Great Danes and German Shepards but some small breeds were also affected. There have been over 500 reported cases of DCM, The food brands linked to this were: Acana, 67; Zignatue, 64; Taste of the Wild, 53; 4Health, 32; Earthborn Holistic, 32; Blue Buffalo, 31; Nature's Domain, 29; Fromm, 24; Merrick, 16; California Natural, 15; Natural Balance, 15; Orijen, 12; Nature's Variety, 11; NutriSource 10; Nutro, 10; Rachael Ray Nutrish, 10.
The FDA is still investigating how specific dog diets may be linked to canine heart disease and have not asked any companies to recall their products. They did find dog diets that include peas, lentils, seeds or potatoes as main ingredients were most frequently associated with the issue. The Food and Drug Administration wants pet owners to be aware of what’s in their dog’s food.
