What is rawhide, really?

Rawhide is made from the inner layer of cow or horse hides — a byproduct of the leather industry. To make it chewable and shelf-stable, it goes through an extensive chemical process: soaking in lye or ash solutions to remove hair, bleaching to whiten, then treated with artificial flavors and preservatives.

What is a bully stick?

A bully stick is beef pizzle — one ingredient, dried. No chemical processing, no bleaching, no artificial flavoring. The entire manufacturing process is: source → clean → dry → cut.

The digestibility gap

This is the most important difference. Rawhide is poorly digestible — when softened by chewing, it can form a gummy mass that expands in the stomach and intestines. This is why rawhide is associated with digestive blockages, vomiting, and emergency vet visits. Bully sticks, by contrast, are fully digestible and break down safely even if swallowed in pieces.

Head-to-head

• Ingredients: Bully stick = 1. Rawhide = multiple, including chemical agents.
• Digestibility: Bully stick = 99%+. Rawhide = poor, risk of blockage.
• Processing: Bully stick = dried. Rawhide = chemically treated.
• Nutritional value: Bully stick = high protein. Rawhide = minimal.
