Patented Brake-fast dog food bowl design prevents your dog from wolfing down their food. The simple obstructions make dogs slow down to eat and makes the animal feel more full, reducing instances of 're-eating'. The product is made in the U.S.A. out of recycled plastic and is Veterinarian tested and recommended. Bowls will hold kibble or canned food as the small can hold 1.5 cups, medium up to 5 cups and the large up to 8 cups.
