"Barkworthies grade-A, naturally shed elk antlers have a smaller profile appealing to more dogs and a lower price point appealing to more owners. Barkworthies Elk Antlers are dense, durable dog chews that will give your dog hours of chew time, beneficial vitamins and minerals as well as cleaner teeth! Our American-sourced, naturally-shed elk antlers come from the Rocky Mountains. After they're collected, they're simply washed, cut and packaged. We also round any sharp edges to make them extra safe for your dog. Barkworthies Elk Antlers are highly durable and are will last hours or days for even the most aggressive chewer. Each antler is filled with soft marrow and contain essential nutrients such as zinc, calcium, manganese and iron that your dog needs for a healthy, long life. Their tough, textured surface helps remove tartar and plaque while massaging the gums. Most Barkworthies' all-natural dog treats and chews are completely preservative-free and additive-free. Please note that this product is not for human consumption. Please supervise your pet while giving a treat or chew and dispose of properly if it becomes a choking hazard or develops sharp edges."
