ChewABone Bones are made from the best quality rawhide, under strict quality standards and supervision. Rawhide chews are a popular treat for dogs. They help keep your dog's teeth clean and respond to his instinct to chew. Chewing also keeps dogs' jaws strong, teeth clean, and breath a bit fresher. Dogs that chew regularly on rawhides and other bones or toys have less plaque and tartar build-up on teeth.
