Our Elk Antlers for dogs are handcrafted to provide your pup a safe, size-appropriate chew without any unpleasant odor, grease, or mess. Available in Small, Medium, Large, and Extra Large to suit your dog’s size. Primal Elk Antlers are humanely sourced from United States forest floors. Elk Antlers are a 100% natural product, which means it’s normal for them to vary in shape and appearance.
