I have 2 boys and my Dexter CAN be the way with me. He worries me when he pants and cries so hard. I worry he'll hyperventilate. Try putting a radio on in the same room as your babies when you leave them. It seemed to help my boys a lot. I think Yorkie boys in general are a bit more mommy clingy than girls are so that is probably why he seems different than your female. Good Luck with him!
