Introducing Beef Spiral Tendons to Best Bully Sticks! These are the spiral shaped curly version of our popular Beef Tendons (Achilles Tendons). They are odor free and come from the same all natural free range cows as our bully sticks. Although they are thinner and do not last as long as bully sticks, they are great tasting all natural chews at a great price. The spiral shape increases the dogs ability to hold onto them and creates more friction in the mouth to assist in removing plaque and tartar. These treats range from 8 to 11 inches in length. Available individually or in 10 Packs.
