My dog lays around sulking when my Wife and Girls aren't home. It's almost sad. I'm the one he clearly knows is Alpha in the house and will take him outside and let him roam the neighborhood as he will stop dead in his tracks for me if a squirrel or other dog is coming...yet for some reason he is only happy around the girls.

On the flip side my Wife says he paces around the house going from door to door when I'm not home. We presume it's to make sure the Girls are all safe. He has never done this with me. It's funny how his entire attitude changes based on who is home.
