We've tried the Gallileo bones. While they held up better than the regular large Nylabones, by the end of the day, we had shreds of it everywhere. Plus Chipper, who's our most non-stop chewer, seemed to swallow a lot of the tiny shreds which I did not like.
I'm sorry. It's a shame the kennel will not accomodate a bumper from a '57 Chevy. But what about a Geo Metro?
