Provide hours of interactive and fun-filled chewing to your dog with the Everlasting Treat Ball. Made of soft, yet durable puncture resistant materials, it is meant for even the toughest chewers, and the unique design allows it to wobble and roll around erratically, so your dog can enjoy chasing it. It's great to use for preventing destructive boredom and irated behaviors such as chewing furniture, or to simply keep your dog happily occupied. Fill the ball with Everlasting Treats, dog food, or your dog's favorite snack. Everlasting treats can also be inserted upside down into the center cavity of the ball as a bigger challenge for your pooch.
