Can anyone suggest safe bones (or chew toys) for my dog to chew on?

I have a large dog and she has broken teeth. I don’t give her any bones to chew on because I’ve noticed blood on them after she has chewed awhile. The only thing I allow her to have are the rope bones but she eats them and they don’t seem to digest very well. Are there any good alternatives to regular rawhide bones to help satisfy her craving to chew?
