tler chews can last for months as your dog gradually grinds them down slowly over time.
Like all natural products, there is some degree of size variation, but on average the large antlers are about 5-8" long ad the small are about 3-5" long.
All these factors allow Barkworthies™ to be a premium quality product that is "Naturally Worth Barking For!"
As with any hard chew, Elk Antlers are very hard and can break teeth if your dog works them too agressively. Once the chew is small enough to swallow, it should be taken away and given a new one to replace it.
