Deluxe Naturals Elk Antlers for Dogs are naturally shed and collected in the United States of America. All of the Deluxe Naturals Elk Antlers for Dogs are excellent chews for your dog. Elk antlers are composed of a bone-like material that regenerates every year, a process known as "branching out" before being shed. Elk antlers are rich in calcium, phosphorus and protein derived from the marrow of the bone. The chews keep dogs' teeth clean and their bones healthy by providing a suitable texture for scraping and nutrients for nourishing their bones. Natural, odor-free, and long-lasting elk antler dog chews are irresistible to dogs and help them stay occupied for longer periods of time.
