I bought one of these for my boyfriend's dog, Robbie. He is a pit bull/lab mix, and generally chews through everything in seconds. Kongs last longer, but will also be destroyed eventually. I bought the Hurley, curious to see how it held up. Immediately, it was clear that Robbie loved this new toy. The shape was good for tug-of-war, for bouncing around, and for holding down with his paws while he chewed. Two hours later, there were puncture marks around the ends. The toy lasted a week of diligent chewing, and then Robbie finally managed to gnaw one end off.
Overall, this didn't hold up as well as a Kong, but he LIKED it better than his Kong. He was clearly heartbroken when I took the broken Hurley away and gave him his Kong to chew on. I'll take advantage of the guarantee, but next time I'll try the Huck and see if that lasts better.
