We found our dog Max on the side of the road and my husband couldn't resist so he is part lab if not full lab. He loves to chew up and tear up things so I looked on line to find some kind of toy he could not tear up or chew up. For Christmas, we bought the Hurley, Tux, and Bumi for him. He loves them. We have only had them for about a week now and he plays with them everyday. So far there is not even a tooth mark. We even took the toys with us when we went to visit my husband's parents and Max and one of their dogs played tug of war with the bumi, but still no teeth marks.
