Bear with me, this one's a little obscure: For those of you who have owned males and females over the years, a question: Do you notice differences in their behavior that you would attribute to the sex? In other words, how are they different when it comes to personality? Is one easier to train? More sociable? More or less outgoing?

In my house, I've come to the conclusion that my females -- Lucy the senior Chessie and Jillie the adolescent Yorkie -- are, for lack of a better word, clingier than my male, 8-year-old Eddie. Those two follow me around more than Eddie and are less independent -- a good thing -- on unleashed walks.

An example from this morning: I got up about 3 hours earlier than normal and popped out of bed in what was the middle of the night for me and my dogs. Jillie, who sleeps on the bed, immediately followed me out to the front room. Lucy, who snoozes in the living room, popped up and followed me around as well.

Eddie, meanwhile, didn't budge from bed.

It's tough to say what that means. Maybe Eddie's just lazier. Maybe Jillie and Lucy were hungrier and thought it was meal time. Or maybe the girls are just more curious. I don't know. But, in my house at least, there's a difference.

Interestingly, I posted this same question on a Yorkie forum -- and no one agreed with me. If anything, their males follow them around more than their females.

Any thoughts on this?
