This dog bowl is made of stainless steel and is one of the good dog bowls. Stainless steel not only protects the dog bowl from rust, but each dog bowl does not contain other toxic substances. Non-slip stainless-steel food bowl for puppies, dogs, cats ect. To prevent skidding, we added permanently bonded high-end silicone ring to the bottom. This skid-proof design prevents sliding-tipping during feeding time and also protects floor. Suitable for dry coarse ground food, wet food, snacks or water.
