It is too bad that you didn't get her at eight weeks instead of 16 weeks. There is no telling what they let her do once she was out of the whelping box.
You will have to start over as if she was eight weeks. You can tether her to you, close off rooms, etc. But you will have to start over with this girl because she was never taught the correct way to begin with.
