My girl, Spirit, an Australian Shepherd, 7 months old seems to go crazy at night. From 8pm to most of the night she wants to go in and out, barks when out comes in and barks to go out again. It's keeping us and the neighbors I'm sure up. During the day she is well behaved, as well behaved as a 7 month old Australian Shepherd can be but at night there is no controlling her. She gets plenty of exercise, I think, but it's almost like sundowner in alzheimers disease.
