Rusty is a big muscular 100 lb powerhouse of a dog. Although he has been able to chew the end of the toy off, this has far outlasted anything out there. I will not mail this toy back to the company to take advantage of the money back guarantee because he loves this toy so much and will not part with it. I recently purchased the huck and that is holding up pretty well, but I think I am going to purchase another hurley for him. The only thing that would make this toy better is if it came in an extra large size for the stronger breeds.
