Good that she's eating / drinking!
( Mine did the same thing when he had liquidy diarrhea...he asked to go out, then laid down outside and refused to come back in.
( Normally he likes to lay in our bedroom or the hall right outside the bedroom!)
So, they are clean and they have a strong instinct to not soil in the house...
I am not as good as you, though! I dragged his dog bed outside for him (the ground seemed so hard) and went to bed!
Morning came and he came in the house like nothing happened...couple more days of soft poo, and then life went back to normal...
I guess I would probably have stayed out to watch him if I thought he ate his dog bed though!! I never did figure out what he ate.)
