Crate her! She is just not ready yet to be out of the crate. It may take another 6 months or so, and then she will be ready.
I would also suggest that even though she listens well, that you get signed up for obedience classes. Honestly, you will have fun with her. You will be amazed at how much this breed wants to learn....and how little you really know.
It will also help to bond, and who knows you may even catch the obedience bug and get a CGC on her, or a Rally-O title. The more obedience training the dog has, the more fun it is to have that dog around.
