Poor baby. I know what you mean, my little Shoshona is much the same but in my case she is such a Mamas girl. I wish I had suggestions that would ease her pain when your away....Maybe your wife could spend some extra special time just with her...maybe take her for a 'girls day out', lunch at a drive thru, maybe a little shopping at a pet store, things like that. It might just help comfort her. Oh, I know. Leave an old sweatshirt of yours around so she can sleep with that. Your scent will be on it and she might find that comforting. You could try calling but she will likely worry more thinking you've been changed into a phone receiver....There is a treat dispenser called a Talk to me ball where you can record your voice which will play as the dog pushes the toy around....maybe that would help???
