Buck Bone Organics Elk Antler Rope Toy ensures your pup has fun, long lasting play sessions. It's made using an Organic Cotton Rope and features 2 pieces of Elk Antler. The antler section is excellent for chewing. The antlers are naturally shed and hand picked from across the USA. Each year wild bull elk across the U.S. naturally shed their antlers, leaving behind an incredible natural resource that is a natural chewing option. It's naturally loaded with calcium phosphorus, manganese and zinc. Not only do these antlers have excellent flavor, they also can help clean teeth and maintain fresh breath.
