One of our dogs (a rottie/blue heeler mix) gets teribly sad when my husband is not home. He will sit out the window and just stare waiting to see his car. When my husband is home he wants to play get petted and is very social, but it's like someone is flipping a switch and he is the opposite when my husband leaves. We are not sure what to do about this, and we sure as hell can't get Ceasar Milan to come over! Any suggestions to get him to be the fun loving dog he is ALL the time?
