They look much like a circular bully stick (rings), but are made of gullet. They are naturally high in glucosamine and chondroitin and as with all of our dog chews, come from free range grass-fed bulls. They are approximately 6" long (although they do vary) and 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). We hope you give 'em a try at Best Bully Sticks!
