Redbarn Antlers are from wild, free-roam deer who naturally shed their antlers. Redbarn Antlers originate in Canada and are naturally rich in phosphorus, calcium and other minerals. Whether you choose the extremely durable Solid Antlers or the split Center Cut antlers with easier access to the marrow, your dog will love this delectable natural chew. These chews are long lasting, odorless, and all-natural. Solid Antlers are ideal for heavy chewers. Regular chewing also helps promote your dog’s dental health!
