I have a boy and a girl that are brother and sister. Hobbs is 10 months old and SUCH a cuddler! He would lay with you and cuddle all day if he could. Hootie is my girl and she is only 13 weeks old, so right now she is a cuddler, but who knows what the future may bring!

My parents, grandparents, and sister all have female yorkies they are all VERY independant.
I think it has a lot to to with how you raise them.
I know it is just a cute little saying, but I've always heard that female yorkies "love" you, but male yorkies are "in love" with you. Does that make sense?
