Bully sticks and rawhide are both popular dog chews, but they differ significantly in digestibility and safety. Bully sticks are fully digestible and made from a single ingredient, beef muscle, making them a safer and healthier option. Rawhide is made from the inner layer of cow or horse hides and can pose a choking risk or cause digestive blockages if swallowed in large pieces. Additionally, rawhide may contain harmful chemicals used during the manufacturing process.
