What type of bones did you get?
I give raw frozen knuckle bones and marrow bones as recreational chews and I don't worry about my poodle because she just gnaws on them. Delgado though is a heavy chewer and therefore I watch him to make sure he doesn't crack anything off the bone
As for the age question, I don't have a problem with puppies having bones.
