The original 100% natural antler dog chew. Stagbars do not splinter. They wear down very slowly with the teeth's grinding action and siliva into tasty morsels. Always choose the right size for your dog. As with any chew, always supervise your dog. Makes sure your dog is gnawing and not bearing down hard. Discard any remaining small pieces. Do not leave the chew outside in the elements. Large, for medium to large dogs.
