Durapet Slow Feed Bowl - Stainless SteelDurapet Slow-Feed Bowls are made of high quality, heavy-duty stainless steel with a permanently molded rubber ring on the base that prevents the bowl from sliding across the floor and creating undesirable noise. The Slow-Feed Bowl design features a dome in the center to make dogs eat around the obstruction, slowing their feeding. Eating more slowly improves your dog's digestion and nutrient absorption.
