Stimulate your pet with the interactive Bouncy Bone toys. The design of the durable nylon bone & rubber ball provide dogs with an extended chewing experience – the Gnawhide treats last longer than giving treats alone & 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.
