Beef 6" Bully Stick. The ultimate chew for dogs. A protein-packed 6" of pure bull penis. It doesn't get much better for a pet parent that knows their dog can't do bones but still wants to give them a good chewing experience. Our bully sticks are all odor free because if you haven't been around a bully stick that isn't odor free... don't. With odor free you have the convenience of treating the chew to your dog in the same room. It enables you to keep an eye on your pooch while you do your thing.
