The Goughnut is sure to have your dog go nuts over it! The super dog toy is the ultimate in play time toys. The durable rubber is able to stand up against the toughest of chewers. The Goughnut also has an innovative design that allows owners to see when the rubber has been compromised. Inside the green outer rubber lies a red center. If your tough chewer is able to expose the inner layer, Goughnuts guarantees a replacement! If the durability doesn't get you, the fact that Goughnuts can float, are recyclable, easy to clean, and full of fun might change your mind!
