I just wanted to update..Lucy spent the night at the apartment last night and she did great! Was very at home and played and cuddled like she would normally do at our house. She even slept in her "big girl" bed that I bought for her a year ago and she never used! I put it by my bed so that she would have the option of sleeping with me or in her bed and I was so proud of her. She did bark a little bit when she heard noises but stopped when I told her "no". And she did not have any accidents! I thought it would be hard to transition her back to using a leash but she did so great that I just had to brag about her. What a smart little girl.
