This style of chew is cut from the tines of a Red Stag antler. The tines are the part of the antler that comes out of the beam of the antler. 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.
