I have these little rawhide "chips" in the shapes of bones... They come in all sorts of colors.. and I give my kiddos Nylabones but not the small ones.. Usually the regular size.. That way they have the chew on it and can't just bite hunks off.. If it doesn't fit in their mouth, the likelihood of them snapping a piece off is slim (but they are supervised ALL the time - someone is always here watching them).
I have always given rawhides... Some dogs can tolerate things that others cant.. I remember my first yorkie could eat every rawhide under the sun but when she got those little 10 cent sticks (they come in beef, cheese, bacon, peanut butter, etc) she would vomit wildly.. The first time, I didn't think it was them and then a few weeks later, gave her another one and same thing...My kiddos now can eat them just fine, although I don't buy them anymore (bfs mom gave them to them).. I just think it depends on the dog, the supervision, and the treat in question...
