Power Chewer Dog Toy: The KONG Extreme Goodie Bone is a dog chew toy designed for medium dogs and constructed with ultra-durable black rubber that can withstand powerful chewing. It helps keep your dog by catering to their need to be mentally and physically active. Great for Stuffing: The ends of the KONG Extreme have patented Goodie Grippers that allow the toy to be stuffed with KONG snacks or filled with Easy Treats. Bone Substitute: The Goodie Bone is ideal for dogs who love a classic bone. With the shape of an actual bone, this safe and strong dog toy is a perfect alternative. It remains solid against a strong biting force but is gentle on the teeth, protecting their dental health. Vet Recommended: Recommended by vets and trainers for dogs with problem behavior or separation anxiety. The KONG Extreme Goodie Bone helps satisfy the natural urges of dogs to hunt, chase, and gnaw, keeping them happy and busy for hours whilst their owner is away.
