The KONG Dental Stick's unique design is shaped to clean your dog's back teeth. It is made from the same strong red rubber as the Original KONG toy. As the dog chews on it, the ridges gently help scrape plaque away from the teeth and gumline. With exclusive Denta-Ridges™, this dental dog toy goes to work while your dog plays, chewing away happily. Made of durable, natural rubber. KONG Easy Treat Paste can be used inside the grooves, if desired, for extra enjoyment.
