Bonehead® Large is a chew accessory specifically engineered to work with the original® Himalayan Dog Chew®. Bonehead® can also hold other chews, like bully sticks and carrots. It’s easy to use, simply use a screwdriver to loosen the screw, slide in the chew so that it’s centered in Bonehead®, and tighten the screw back down. Now give it to your dog to enjoy!When they have chewed as much as they can, take Bonehead® back and remove the small piece of chew locked in the middle. Soak your chew in warm water for five minutes, pat it dry and toss it
