Good for: The Large Split Elk Antler is a very durable chew, suitable for dogs weighing 40+lbs. The center marrow of the elk antler is exposed for easy chewing in the middle. Elk antlers have a higher ratio of soft inner marrow compared to the extremely hard outer layer, meaning that it won't be as dense as a deer antler. Split antlers are recommended for dogs who might not be used to chewing on antlers; however, a split antler is not as durable as a whole antler.
