Best Buy Bones' NOT-RAWHIDE dog chews are only sourced from the face and head of the beef cattle. We finish these all-natural dog chews with a minimal amount of processing. Once rendered, these long-lasting dog chews are cleaned and dried/baked, removing virtually all moisture to provide the rawhide-alternative roll with a stable shelf life. These single-ingredient treats are truly natural and can be enjoyed by most dogs without risk of them ingesting toxic chemicals.
