Dura Chew products are one of the few toys that have been able to withstand my 11 month old Irish Setters termite teeth. She loves this and other than some teethmarks, it is as good as it was a mo th ago. Most toys don't make it a day so e don't make it an hour but the Dura Chews hang in there. I agree with the last poster--this thing can break a toe if they drop it on your feet and pretty painful if stepped on :-)
We have two big dogs, a Italian mastiff and a Rottweiler. They are both voracious chewers. This toy started out fine and they could chew on it, but then our mastiff started to chew the white ends off and the red piece quickly fell apart and the other white ends fell out. Quickly went in the trash after that!
I use this for my 11mo old Lab along with her elk antler for chew toys. So far, it hasn't even come close to being destroyed after 6 mo of heavy use. My girl happily carries it around by the center and even likes tossing it around. One note though. This thing is HELL on your feet if you step on it, so be wary. My husband and kids have come close to throwing it out because of the pain that it has caused them.
