The squirrel's tail features cleaning bristles that help remove plaque and tartar while chewing. Multi-textured design provides dental stimulation while satisfying a dog's natural urge to chew. Designed for powerful chewers. For best results and optimal cleaning, use daily. Introduce the bristle brush for a limited amount of time and supervise use until you are confident your dog can chew safely. If your dog is a more powerful chewer, limit the amount of chewing time and discontinue use if damaged or torn.
