These all-natural chews are durable enough to keep even aggressive chewers happy and occupied. Plus, unlike traditional rawhide, they're highly digestible and virtually Odor Free. The Full Cane is minimally processed from free-range grass-fed cattle. Its unique shape and texture promote good dental health while helping prevent bad doggy breath. Most Barkworthies' all-natural dog treats and chews are completely preservative-free and additive-free. Please note that this product is not for human consumption. Please supervise your pet while giving a treat or chew and dispose of properly if it becomes a choking hazard or develops sharp edges.
