Raven God Bless You, he sure answered alot of prayers that is for sure. You look more and more beautiful, such a wonderful smile, it just melts my heart!!!! Try not to worry to much about the anxiety, whether shelter dog or not has nothing to do with it, its from the trauma she went through, she will come out of it, with the love and the way you work with her, she will go back to normal once she knows everything is really okay.
Give her a very big hug.
