Perfect for heavy chewers
My dog is a heavy chewer and chews through almost all of her toys except for these! She absolutely loves them and they keep her busy!

Dog loves them
Our dog loves these, we do have to purchase them every few weeks because he chews it on a lot. They are very durable but do start to peel away after a lot of chewing and need to be disposed of at that point.

Highly Recommend!!
My Yorkie & my daughter’s pug love these bones!! I replace them when they get ragged in the ends. It’s occupies them after running around playing, and keeps tartar buildup down.
