I own a male Jack Russell Terrier and he destroys every toy he has. I was on Vancouver Island and I saw the Hurley Durable and Flexible toy so I bought it because I am willing to try just about anything. I purchased the toy on Oct 7th, 2009. I noticed the first day he had it that the material was starting to get strain marks in the material and my dog diezel had already broke the material on the outside on Oct 10th, 2009. I pretty well give up on getting chew toys for my dog. now I just need to find a dealer a little bit closer so i can return the toy for a full refund.
