My Samantha used to do this same thing my mom told me to get a pop can put some pennies in it cover top with duct tape. Put it by your bedside.... Tell her good job a couple of times when she barks (the old praise thing) Third time warn her onetime with single word eeeeenough stress the e part the next time she barks shake that can full of pennies , if she barks again say enough again and shake the can again..... I can tell you I only did this twice shaking the can the noise bothered her and she stopped. Every once in a while we give her a refresher course.....lol I think the pennies bother her the way her bark annoys us at wrong time!!!! Hope this helps!
