Premier Busy Buddy Bouncy Bone with ball in the middle is an interactive toy that stimulates your pet. The design of the durable nylon bone and rubber ball provide dogs with an extended chewing experience - the Premier Gnawhide treats last longer than giving treats alone and dogs are stimulated to chew the toy well after the irresistible Gnawhide treats are gone. Toy unscrews to load treats and clean. Comes packed with three sets of treats. Additional Gnawhide treat rings sold separately. Size: Medium.
