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 punch of flavor. They work overtime to support your dog’s muscle development, while the natural act of chewing helps support their Dental health by gently massaging their gums and scraping away plaque and tartar buildup.
