BarknBig Moo-Hoo Pieces otherwise known as Beef Trachea. Purchase this 10oz. bag and provide multiple treating opportunities. Trachea is shown to contain natural glucosamine. The beauty of natural glucosamine is the fact that it is biologically available for our pets' system to put to use. They have a nice crunch that entices the pups to eat it right away. For you large dog parents, make sure you know if your dog can chew a product like this instead of swallowing. It will break down easily if they crunch on it. We trim much of the extra fat from around the pieces leaving you with a fairly clean, less greasy trachea chew. Enjoy! (watching of course)
