100% beef pizzle, sourced from free-ranging, grass-fed South American cattle. This odor free bully stick will not smell while your dog is chewing it. Bully sticks are highly recommended for new puppy owners as well as newly adopted rescue dogs. They won’t be able to resist chewing on a bully stick and this will prevent the puppy from developing bad habits like chewing on shoes and furniture. Great for anxious or active dogs, as chewing calms dogs down and relieves stress.
