Bonehead is a chew accessory that is specifically engineered to work with Himalayan Dog Chew but it can hold lots of other chews too from bully sticks to carrots. It s easy to use simply use a screwdriver to loosen the screw slide in a 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 from the middle soak it in warm water for 5 minutes pat it dry and toss it in the microwave for about a minute to make a cheesy puff for your pup. Always be sure that you cool microwaved puff for at least two minutes before giving it to your dog. Do not microwave Bonehead.
