The PetSafe Forever Bone Dog Chew Toy is made from heavy-duty nylon and vanilla-scented rubber that is tough enough to withstand even the most aggressive chews. The unique Snap Fit cups grip delicious natural rawhide treat rings and hold them in the center of the toy to provide a fun and tasty way to play. The textured surface provides a different texture to experience while gnawing or chewing. The combination of treat and chew toy challenges dogs and helps redirect destructive chewing behavior. The PetSafe Forever Bone Dog Chew Toy is available in small, medium, or large sizes so you can choose the perfect size for your dog.
