Like all Redbarn Bones, this Bully Coated Bone is a 100% real beef femur bone, naturally cleaned without the use of bleach or other harsh chemicals. Once cleaned, it's coated in Redbarn's signature bully gravy prepared with real Redbarn Bully Sticks. So give your dog a bone they not only love, but supports their dental health, and reduces stress and boredom as they chew!
