I have that sorta kinda same problem
.. My boy Yorkie will go NUTS if he's not the one i'm cuddling or kissing. While My Girl Yorkie loves to cuddle, she doesn't care who it is that's giving her a belly rub.. as long as it's me or daddy. And for my Girl Maltese, She is such a baby! She loves both me and her daddy, but she just neeeeds the attention!
So it's a toss up between the littleman and My Maltese. they love to argue over who gets to cuddle with mommy.
