My pups love these! These are super hard to find in the store, especially in a two pack and this size. My little Shitzu has had one since she was tiny and it is kind of an emotional support thing for her and when she lost it she was so sad that it was awful. I searched every where, every store around us for the little ones like this and could not find one. So when I seen this package and with two, for this price, I jumped on it! Now I have an extra one to put up just in case she loses one. You cannot go wrong with Hertz toys for your furbabies.

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.
