Stainless steel makes the best dog bowls for puppets. They can be easily cleaned in your dishwasher and boast of more pros than cons among the other materials. For a better choice, you can consider a bowl with a stainless steel bowl mounted on a silicone or melamine casing that gives it a better outlook than the silver colour of the polished steel. It's also essential to avoid leaving the bowl outdoors to prevent corrosion and accumulation of rust.
