Keep your dog's teeth healthy and clean with your Nerf Dog Spikey Ball. The spiked ridges clean teeth as dogs chew. You can provide extra enticement by adding a little of your dog's favorite sticky treat to the toy (we recommend protein-based peanut butter). The spikey toy is molded in durable thermoplastic rubber, making it extra strong, so it'll stand up to extended chewing. Textured ridges make it great for toss and fetch too!
