my yorkie loves nylabones they're just about the only thing he can have, he is such a strong chewer he gets through things sooooo fast so i think nylabones are the best toy, i get the ones that are really thick called prince and they are blue and round, they are for powerful chewers... Tyler does get bits off but only shavings like rice sized which is ok according to the leaflet in the packaging! nylabones are vetenary approved also i think so its the only toy i trust really and they are great for their teeth too!
