We got this for our dog as a joke after being fixed. However, the quality of this was equivalent to a regular kong. The rubber is quite thick and the toy is medium/low bounce which is what we wanted. Our dog absolutely love it. However, because he is a chewer, he did end up breaking the toy and we had to remove it so he would not swallow any pieces. It is durable, but it will still fail for a avid chewer like a puppy.
