I personally don't know of any that are safe. Mine are both very aggressive chewers, and they always chew everything up and swallow the pieces. So, that scares me. Even if they say "edible", "completely digestible", etc. Who or what can you trust? If you have yorkie babies, then the harder chews are probably safe, as they can't chew them up as well as the older yorkies. My girls are so unhappy that they can't have greenies anymore. Poor things. They just don't understand. They have always had a piece of one before they went to bed at nite. Now I just give them one of their treats. I went to Petco the other day and got $31 worth of different treats! There were about 8 different kinds. Out of all of those, they only like about 3! Oh, what's a yorkie mother to do!
