This style of chew is cut from the base of a Red Stag antler. The base is the part of the antler that attaches to the head of the deer, and provides the foundation for the antler growth. The outer edge of a Red Stag antler is dense, but the center contains a soft marrow. This combination provides a great all purpose chew. The dense outside provides hours of chewing time, while the soft marrow is the reward that your dog will look forward too.
