If your pooch loves our gullets, these will be a huge hit too! They are gullet, wrapped in the shape of a pretzel. They are naturally high in glucosamine and chondroitin and as with all of our beef dog chews, come from free range grass fed bulls. They are approximately 3" wide x 2" high (although they do vary) and do have a slight odor that dogs go absolutely crazy for! (Although these are a chew, they do have a softer consistency and will not last as long as bully sticks or trachea).
