Give your dog something good to chew on. Made with tough, durable nylon, the Nylabone DuraChew Bone dog toy was designed for powerful chewers. It provides long-lasting enjoyment, satisfies the natural urge to chew, and encourages positive chewing habits. Plus, the bristles raised on this long-lasting dog chew toy during chewing promote clean teeth and 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.)
