It's a little stranger than that. Mandy was my first wife's dog and I never realized how completely hers and not mine until my wife died and Mandy refused to acknowledge that I existed. She'd run out to get in the car of any woman who visited. I gave her to my daughter in law and they worked hard to get her to function again. When my daughter in law got pregnant she took up station between her and the door throughout the pregnancy. From the granddaughter's birth Mandy has been a constant guardian. Her next favorite people are my two sons. everybody else, including the daughter in law is after that. It seems that she still misses her original "Mommy" and can tell who is a blood relation.
