BarknBig Premium Beef Tendon Chew Strip 12ct. These are an impressive 10-14" in length. For mid to large size dogs this is a natural way to supplement high concentrations of hyaluronic acid which the body uses to manufacture its own glucosamine for hip and joint health. For dental health, we call it nature's floss due to the stringy fibers as it breaks down. Our Tendons have no odor much like most all of our products so enjoy watching your dogs go to town without having to quarantine them outside or in another room due to the smell. Buy in bulk and save yourself some money.
