I bought this for my destructive 4 year old shi-tzu/cockapoo mix, and its great! I used to buy her cheap stuffed toys and she would have the stuffing out in less than an hour. So I saw an ad for westpawdesign in a magazine and gave it a try. At first she didn't really play with them for a couple days, I guess because it is different material. But she finally figured out they were toys and now she loves them. I've even watched her try to chew them to pieces, without success! I bought her the zisc and the hurley, and she likes the zisc the most. I also like that if they get too grungy I can stick em in the dishwasher. :)
