Treats and chews
What are bully sticks made of?
Last updated 23 September 2026 · How we write and check this
Short answer
Bully sticks are made from a bull's or steer's pizzle, meaning dried muscle tissue rather than bone, cartilage, or skin, which is then cleaned, stretched, and dried or smoked to create the finished chew. This muscle based composition is why bully sticks soften with chewing rather than remaining rigid like a bone or antler.
The specific animal tissue involved
Despite various marketing names, bully sticks come from the same source tissue, cleaned and processed through drying, sometimes with additional smoking or baking steps depending on the manufacturer, which affects the final texture, smell, and how quickly the stick softens once a dog begins chewing it.
Why the tissue type matters for chewing safety
Muscle tissue is naturally more pliable than bone or antler, which is why bully sticks flex and soften progressively under a dog's bite rather than staying rigid, giving them a fundamentally different, generally lower risk profile for tooth fractures compared to harder chew categories.
Variation between manufacturing processes
Baked bully sticks tend to be denser and less odorous than air dried versions, while single sourced products, meaning from one identified farm or supplier rather than a mixed unspecified source, are generally considered more consistent in quality and lower risk from a hygiene standpoint.
Key takeaways
- Bully sticks are made from dried muscle tissue, not bone, cartilage, or skin.
- Muscle tissue's natural pliability is why bully sticks soften rather than staying rigid.
- Baking versus air drying changes the final density and odor of the finished product.
- Single sourced products are generally considered more consistent in quality.
