This toy features a nylon bone with a rubber ball in the center. It unscrews so that you can slide Gnawhide rings on either end of the bone against the ball. This toy comes in three sizes: small, medium, and large. Replacement Gnawhide rings are available and sold in packs of 12-24 depending on the size of the toy.

Those who have purchased this toy say: Dogs can remove the treats pretty easily so it’s not much of a challenge, but the Gnawhide rings will take them a bit to eat. Be prepared to purchase refills. The Gnawhide rings aren’t sticky and messy, so some owners allow their dogs to eat this treat on the furniture. Dogs will still chew the toy for awhile because they like the bone. The ball can be used as a separate toy since the toy unscrews. It’s recommended for aggressive chewers.
