I have 1 male Yorkie, and he is my little man, we also have 2 Rottweilers a male & female, i don't think there is a preference, I love them all the same and they all love each other, I'm also planning on getting a girl yorkie in the near future for Nemo, he love to play with Simba & Nala but I think he would have more fun , with a doggie his size
