I bought a large Hurley from our local pet supply shop. Our 50 lb mix, Provo had destroyed many of the toys they carry that the staff started using him as a "tester" for their chew toys. I can't tell you how many times I had come home hopeful a new toy would last only to find it in pieces 15 minutes later. I was bringing back a shredded Level 8 Tiger Tested ring when they recommended Hurley. I liked the weight of it and thought the simple design would have a chance. That was about a year ago. There are a few "divots" in the end but Provo has not ruined this toy. He loves to play with it. Thanks for making a great product!
