Today, Bully Sticks are our most popular product - and for good reason! These all-natural, highly digestible chews are made from a single ingredient, beef pizzle (a muscle), and slow-roasted in their own juices for maximum flavor. But they do more than pack a powerful flavor punch. They work overtime to support your dog's muscle development, while the natural act of chewing helps support his dental health by gently massaging his gums and scraping away plaque and tartar build-up.
