Give your dog something good to chew on. This Nylabone three-pack includes two DuraChew Bones and one Dental Chew Bone. Made with tough, durable nylon, the DuraChew Bone was designed for powerful chewers and encourages positive chewing habits. Made for moderate chewers, the Dental Chew Bone has gently rounded dental nubs that promote clean teeth. Not recommended for strong chewers. Both chew toys have bristles raised during chewing that help control plaque and tartar buildup. (Different dogs have different chewing styles and strengths, even within the same breed, so be sure to choose the correct chew size and type for your dog.)
