I'm biased...I love my little
boy Yorkie. He is crazy, playful, and sweet all at once. I had both males and females throughout my childhood, and it is the males I remember most. I had a male miniature poodle until I was in high school who was so smart and so sweet.
My little guy doesn't lift his leg...he squats. I think I just got lucky.
Of course, I wouldn't turn down a girl either. In fact, the little rescue I am currently pining for is a sweet little girl.
