They are all natural chews that are made from dried Yak and Cow's milk. These are hard pieces that I have heard are supposed to last a while for the dog to chew through and are safer than some of the other chews around where pieces can break off and become lodged in the dogs throat. They are similar to the idea of bully sticks. I just gave the chew to my dog and will soon see if it upsets his stomach at all. If it does I will definitely update and let everyone know. |
