We already own a hurley and a tux and have had great results with both of them. I compare them easily to the kongs that last for us. We bought the bumi with hopes that it would prove to be lots of fun, but it only lasted about 10 min. Both of my dogs were excited about it (Standard GoldenDoodles) and wanted to play with it and tug without sharing but it quickly had a chunk out of one end and I had to take it away before they figured out they could eat it. We are disappointed but glad West Paw has a guarantee. We will return the injured bumi and get another hurley.
