Redbarn Natural Bully Sticks for dogs are made from beef pizzle. This beef muscle is savory and full-bodied, which naturally creates a mouthwatering treat for your pet. Our Bully Sticks are slow-roasted to achieve a hardy texture that your dog will happily wag its tail for. Beef pizzles closely resemble the ancestral diet of organ meats. Beyond being a tasteful dog treat, there are a variety of reasons that make our 12-inch Bully Sticks the only choice for your pet.
