These Treats are made of Buffalo Trachea that has been compressed into the shape of a bone before drying. This means they contain all the nutritional benefits of trachea while being even longer lasting as they aren't hollow like traditional trachea.  
Buffalo trachea is high in protein which helps to strengthen joints, highly digestible making it a great treat for puppies and adult dogs. It also helps in promoting dental hygiene by scraping away plaque and tartar build up when chewing.
 
Always supervise your dog when chewing. Please provide plenty of fresh water along with the chew.
