Thanks all!
I'm so proud, LOL. I let her off her leash yesterday and let her have free run of the house to see how she'd do. No accidents and she rang the bell every time she needed to go out, all by herself. Of course now she thinks she owns the house. Anyway, I think I will continue letting her enjoy her freedom, so long as she is responsible. SUCH a load off not having to worry about her peeing and pooping on everything.
