The Bonehead is a Himalayan Dog Toy that holds a chew. Bonehead is specifically engineered to work with Himalayan Dog Chews, but it can hold lots of other chews too - from bully sticks to carrots. The Bonehead is dishwasher safe (top shelf) and is simple to use. Loosen the screw with a screwdriver, slide in the chew so that its centered in the Bonehead then tighten the screw back down.
