Are you walking her? That will be her job. You're in charge, so everything you do during the day tells her so, from the feeding to the control of activity. Do you have a contained area where you can let her out the door unaccompanied at night for a few minutes? It sounds like she was trying to tell you something. Good luck!

Invariably as I have things listed in eBay that aren't going anywhere I wonder what the next step is - donate, or find a use? I was beginning to think about one item I might be able to use - and invariably, it sold overnight! Must do this more often.
