This exceptionally durable bone-shaped chew is designed to stand up to even jaws of steel. Made from the same super-sturdy, puncture-resistant, non-toxic rubber as the black Extreme Kong, it's the perfect toy for the home-alone canine. The Extreme Goodie Bone helps satisfy dogs' natural urges to hunt, chase, and gnaw, keeping them happy and busy for hours while their owner's away. The innovative design features holes with patented Goodie Grippers on each end. Stuff the holes with biscuits, dry foods, or Kong brand Stuff 'n pastes or treats, and watch your dog go to work extracting the contents; the grippers make the "hunt" harder, and therefore more fun.
