I would keep a very close eye on her. Make sure everything's "working" aka passing thru her system. You want to make sure the bone isn't stuck somewhere, causing a blockage.
I've used some bread myself in certain instances. I just wonder with that size dog and bone if something wetter/softer might be a good idea
It was cooked, I did give here some bread right after she ate the bone I read that could help. just have to keep my eye on here, thanks for your responds.
You see any of those symptoms, get the dog into the Vet.
