We crate trained Libby when we first brought her home. It was the first dog we had done that with. It only took a few nights for her to get used to it. Then when she would wake up in the middle of the night to go out, she would whimper and we would get up and take her out. However, now that she is housebroken, she sleeps at the foot of our bed. We have a step for her so she can get up there herself. We sleep with the bedroom door open and she goes out her dog door in the middle of the night if she needs to. She's really a great bed sleeper, much better than other dogs we've had.
