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. Recommended by vets and trainers for dogs with problem behaviors or separation anxiety, 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. Measuring seven inches long, the black Extreme goodie bone is appropriate for aggressive chewers and large dogs, including Labs and German Shepherds. Regularly inspect your goodie bone for cracks or missing chunks, and replace worn or damaged toys to avoid a choking hazard. Satisfaction is guaranteed; if either you or your dog aren't happy with your purchase, return within 30 days for a full refund--Mary Park
