JW Holee Gourmet Dog Toys are inspired by the popular Holee Roller, which encourages dogs to play with their food! The peanut shaped rubber and nylon pieces make for a multipurpose treat and chew toy. The rubber shell has several openings to add your dogs favorite treats. The nylon center has openings for spreadable treats such as peanut butter or canned spread. Nylon can be removed from rubber casing for long-lasting chew toy.
