i bought one of these over 4 years ago - yes, i said 4 years! i have a puggle (pug/beagle) that literally destroys every toy within 24-48 hours (except this and a real marrow bone from the butcher shop, both of which he still carries around after years). he got the head and tail of the stegosaurus chewed off almost immediately, but has never gotten further. i was surprised to read all the negative reviews, and would have probably not bought this for him if i had seen them 4 years ago. i guess you need to know your dog. mine is destructive with toys but not obsessive. it has probably lasted so long because he'll find it and play with it for a while, then forget about it for weeks again until one night he remembers where he hid it and won't stop trying to fit his fat body under the couch until i lift it up so he can retrieve this old dusty dinosaur and chew for another 30 min. i feel bad for those who have had dogs break teeth, but in my case it has not been at all unsafe. i wish i had seen it here and not paid over $10 at the pet store
