So I am really thinking about getting a second yorkie. My little guy is 8 months old and about 4 1/2 lbs. He is so social and loves every dog, puppy, cat, person that he meets. He is not an alpha male at all. If confronted with another dog, no matter what the size, he will submit, show his tummy and then say....."Let's play." Even his trainer at Petsmart says that Derby loves everybody. He is a total love. Anyway, I have always loved boys.....my experience with girl dogs have been that they are moody, snappy, less affectionate, dominant, and they hump as much as the boys do. So, my first inclination is to go for another boy and I think I have one picked out but I want your opinions.......

Is a boy/girl combo better or a boy/boy combo? Who has these combos and is willing to share their experiences? Thank you.
