Brake-fast® dog food bowl's patent pending design prevents your dog from bolting their food. The simple obstructions make dogs slow down to eat. Slower eating makes an animal feel more full and reduces instances of 're-eating'. The Large brake-fast bowl serves Giant breed dogs; Mastiff, Great Dane, St. Bernard, and others. Large bowl is 10" in diameter. These bowls are designed to slide along the floor. Large dishwasher safe bowl is only available in black.
