Bison tendonchews are a great source of Chondroitin & Glucosamine to support healthy joint & bone health. They are freeze-dried to ensure they are not only easy to chew but easy to digest, making them the perfect treat/chew for your pups. As always, we’re committed to sourcing locally and these chews are no different. We source from local Colorado farmers! We never add anything to our chews – no preservatives, salt or sugar, chemicals or rubs. Nothing but the good stuff here! *As with all chews, please always supervise your dog with this, or any chew.
