Built tough - our Tuff Bowl isn't your ordinary pet bowl. This dog bowl is made from super tough double walled stainless steel that's corrosion and rust resistant. It holds up to 5 cups of water or kibble and is super easy to clean. Just put it in the dishwasher (top rack recommended) and it's as good as new. The Tuff Bowl Coral has a silicone base that prevents it from moving around while your dog is drinking or eating from it.
