These are the most unique chew treat on the market today! Each Wapiti Gnaw is cut from “hard” elk antler. Hard elk antler is loaded with many of the same nutrients as earlier growth stage velvet antler but is particularly high in calcium. Wapiti Gnaws offer a tasty chew treat that also aids in dental care. And, in addition to all the great nutrients they provide, Wapiti Gnaws last up to 10 times longer than virtually any other chew treat on the market today.
