Smoked bones can splinter, so it's dangerous in my opinion. For the edible nylabones, I'm not sure. I used to give booda bones to Boris, until he started destroying the whole thing in about one hour. They're supposed to be edible, and disolving in the stomach, but I stopped giving them because when he gets to the end of it he was liable to chocke on them, plus it was just getting way too expensive. Also he got into a couple fights with Tips over one, so it wasn't worth it. I supposed they're ok to give if the dog is supervized while chewing them.
Something else that dogs love is bully sticks, but last time I gave Boris one he chewed it down in about one hour and had horrible diarrhea afterwards, so I'm not going to try again lol.
