Buck Bone Organics Split Elk Antler Dog Chews are nature’s gift for your canine companion. Every year, wild bull elk across the United States naturally shed their antlers, leaving behind an incredible natural resource that just so happens to be a healthy treat for dogs. Buck Bones Organics collects and carefully crafts these antlers into the paw-fect eco-friendly, premium treat! They provide your pup with an excellent source of calcium phosphorus, manganese and zinc. And as your dog chews to her heart's content, the texture of the bone helps scrub away plaque and tartar to promote healthy teeth and gums!
