Containing 2 beef shoulder knuckles and 1 beef crown knuckle, The Country Butcher Beef Knuckle Bone Dog Chew Treats will keep your dog busy chewing for hours. This dog treat is a USA-raised tibia knuckle, dipped in liquid smoke and oven-baked without any artificial ingredients added. These chews are the knuckle end of the beef tibia bone from the hind leg. These bones are appropriate for medium and large dogs and have no artificial ingredients included. They are dipped in natural liquid smoke and slowly oven-roasted to make the perfect chew. Each of these have scrumptious meaty tidbits that will have your dog coming back for more. Gnawing action will help encourage plaque removal from dogs' teeth, while the natural grease from the bone will help improve their skin and coat health.
