The Busy Buddy Bouncy Bone is 3 toys in one: nylon bone, rubber ball, and refillable treat-holding toy. Made from durable nylon and natural vanilla-scented rubber, this toy was designed to satisfy strong chewers. Treat ring refills reward good chewing behavior to encourage longer playtime. New chicken-flavored dental support treats are made in the U.S.A. and help clean teeth and freshen breath.
