My dog, 5 year old and 90 pound black lab, destroys everything and this stands up to him. He can make little indentations in it from his teeth but it doesn't ever puncture. I bought it originally as a treat finder, which isn't exactly what it is - that's my fault for not looking carefully. It's more like a Kong toy with a open hole. He has a Kong too, but since we got this, he prefers it entirely! If you ask him to grab a toy, this is always what he goes for first.
