You could also consider crate training her. I never really felt that was a good option myself until my current lab. We rescued her a few years ago from a local shelter and a friend gave us a crate she had. We knew we would not want to be leaving her lose in the house and after speaking with a lot of folks we tried it.

Actually, when I say 'tried it' I simply put it in the house and left the door open with a comfy blanket for a cushion.

She started sleeping and taking naps in there on her own. She may have been crate trained before. As it stands now though she prefers being put in her crate when we need her 'contained' more than she would like being outside for hours. She doesn't often spend more than a few hours in there at a time but there are occasions where she will spend the day in her crate.
