These Curly Bully Sticks in a pack of 10 are great for both big and small dogs. They are 10" in length and the thickness of most small-standard bully sticks (but will vary slightly). They are great because your pooch can stick their paw in the middle of the curly bully stick, which helps for a great hold while they chew and chew. An additional benefit of these sticks is that they are curly and as such create more friction in the mouth when chewed. These bully sticks are all natural, but do have a slight meat smell! We use exclusively FREE-RANGE grass fed cattle in our Best Bully Sticks natural beef dog treats and dog chews. We believe that cattle should be free range and graze on grass rather than be cooped up in feedlots. In our opinion, this makes for a higher quality product the way that nature intended.
