For the past 5 nights Scarlett has started barking and growling at every little noise (and some things we can't hear) from about 11 pm till well after midnight. I've tried holding her, getting up and watching TV with her, even really vigorous play about 10 o'clock trying to wear her out, with no success.
Any suggestions? I'm tired because it takes me a good hour or so after she finally settles down for me to fall asleep, and our alarm goes off at 6 a.m.
