Bravo! Dry-Roasted Beef Trachea Chews are an ideal natural source of chondroitin and glucosamine. High-quality beef trachea helps build and support cartilage, lubricate the joints, and helps with occasional joint stress due to exercise or physical activity. As your dog chews the trachea, it also helps to naturally clean their teeth. Bravo! Can be easily cut to the right length for your pet.
