I think personalities are going to be different-whether male or female.
My male is more dependent than my female. My female is more of the alpha-well, she wants to be. They fight over that quite a bit. My male is much more lovey than the female-he ALWAYS has to be where I am, on my lap, kissing me. My female could care less if she's on my lap or not. My male is definately my baby-without a doubt. I got a female because I wanted a girly little dog. I think Baxter is more girly than Chloe-Chloe is a tom boy.
My female is MUCH easier to train than my male-much easier by far.
I think the differences in my dogs are personalities and not just traits of males versus females.
