The problem is that at night she will awaken every two hours and begin to bark making it necessary for me to come down to quiet her. I usually will take her out, but often she will just stand there barking
until I bring her back in, so I do not think it is a bathroom issue. I think she realizes she is alone and that is what causes the barking. We have tried leaving lights on all night, or the TV, we even got her a heartbeat pillow, but still she will get up and bark every two hours at night.
