I feel so bad for you! I know some people leave water out all night, but I don't because Roxie is trained to go outside- never in the house. So I do take up water between 8:00pm - 8:30pm, after I am sure she has had her fiill of water because we walk each evening. I take her out the last time around 10:00 pm. After I knew she could hold her potty (and the vet gave me a guideline) when she would wake up- I would just whisper to her " Quite" and she caught on that 2:00am was not the time to wake up. But now she is like an alarm clock and hates to be disturbed
anytime before 6:00 am on the weekends. Plus she is a bigger Yorkie then some at 6.5lbs so she can hold it a good while!
