I have one of each. We originally wanted a girl, but when we got to the breeder's, a boy stole our heart. Several months later, we got the girl.
In this instance, the girl is more of a cuddler. She's about 4 lbs. The boy is my shadow: never far away - always close. But I don't think he was properly socialized as a baby
. He does the best he can, and is getting better. He's just different. He's just about 7 lbs.
The boy is *horrified* if I try to dress him: he freezes in his tracks and won't move. Bella, on the other hand, *loves* to play dress up, and looks peeved when we take her dress off.
Each pup is its own being. It's not that boys are more attentive or that girls are ... they're individuals. Go with an open mind, and leave with the one who steals your heart.
