Have you tried an expen? It confines her, yet gives her space. I know a lot of people here crate train their babies, but honestly, I'm not comfortable with that. I had an ex-pen for Kaji and he slept in it every night, until I gave in.
Ever since I let him pick his own bed, he's choosing the bed over sleeping with me.
I got use to having his furry butt in my bed.
It's also were I kept him when I went to work. He had his food, water, and bed in there. He was older, and already outside trained when I got him so he didn't have a piddle pad in there.
