We ordered 2 Hurleys, a Jive and a Zisk. The dogs love the Hurleys but the Jive was the big hit. They both love that thing. We'll probably have to order another one. They are extremely durable - these 2 go thru chew toys very fast - even the ones rated for tough chewers. They are all holding up very well - no chunks are coming off and actually they are hardley even making any indentations on the toys @ all. The Zisk we will probably be sending back just because neither dog is showing any interest in it. It is well made like the other toys described here but they just are not taking to it. That being said, we cannot be any happier with the quality of the 3 toys our Pitbulls like. I hope they keep holding up as well as they have so far. We will certainly be ordering more product from you guys in the near future.
