I don't really like buying these super hard plastic toys for my dog, but he's such an aggressive chewer that most toys are like throwing away our money. If he doesn't destroy it it's because he doesn't like it. But these last a while. He's had one of these for almost a month now. It has chew marks, and he chewed a couple of small pieces off, but it's mostly fine. He likes it when I spread peanut butter between the ribs. The only other downside (besides feeding my dog plastic) is that it hurts worse than Lego to step on it when you're barefoot.

My dog really loves this. She has been chewing on it since it first arrived and it still hasn’t been chewed up. This toy is truly indestructible.
