The Redbarn Odor-Free Bully Stick is a 12-inch, single-ingredient dog chew. Bully sticks are long-lasting chews that satisfy the urge to gnaw, and this version is made to have less odor than standard bully sticks. Always supervise your dog while chewing, choose a size suited to your dog, take the chew away once it is small enough to swallow, and keep fresh water available.
