We've been having the same problem around our home the last few weeks. Dakota sits at the end of the bed and whines until one of us wakes up. If we seem to take to long, she'll come to either side of the bed and put her head right near one of our ears and do it more. Sometimes she'll even flat our bark at us from the end of the bed. It's rather annoying. They always get their trip out, but sometimes it just wears us down from not getting a full night of sleep!
