A "backwards" training day as I read on another post. But in your case, congrats - she is settling in since you have only had her just less than a month. She is starting to relax and does not need to feel to have to be on her best behavior or you won't keep her. You may to ease up a bit, take a training break - go for easy walks, letting her sniff, play with her.
