Stainless steel dog bowls are by far the most durable and are also dishwasher-safe. Plastic bowls are generally not recommended for many dogs, as bowls made of plastic can easily be chewed or scratched by your dog, leaving a place for bacteria to build up.

Additionally, some dogs may develop an allergy to the plastic, resulting in a mild skin reaction on the chin or face. Therefore it is recommended that plastics must never remain in contact with food, as it may make your dog food poisonous.
