Elk naturally shed their antlers every spring and grow another set each year. These shed antlers are collected and kept fresh; the darker the antler, the fresher it is and the better it is for your dog. These 100% natural antlers have no added colors or flavors; they are completely unprocessed. Dogs absolutely and instinctively love antler chews because of their taste and you can feel great about giving them mineral-rich antler chews because of the numerous health and hygiene benefits. These long-lasting chews won't splinter or chip and are available in two varieties - whole and split. Some dogs may prefer the split antlers, because they can get to the marrow faster. Please supervise your dog when they are enjoying antler chews and remove the chew once it is worn down to a size that's small enough to swallow or choke on. Periodically check the antlers for sharp edges, which can be easily removed by rubbing the antler against concrete or sandpaper. All antler pieces will vary naturally in shape, circumference color, and weight. Choose from whole or split antler chews. Sizes: Small for dogs 5-20 lbs. approx 5" long.
