Does your dog act sad before you leave to go somewhere?

I very seldom leave my dog home alone, at most only 2 hours twice a month. Our dog is very lucky since there are 5 of us in the house and we all take turns looking after her. She also has a favorite spot, a plush chair that is located beside a window. She loves sitting there and watching the neighbors kids as they play. My children, even my teenager all prefer staying at home rather than going out with friends so chacha our chow almost always has a playmate within the vicinity.
