i have 2 females (one being a maltese and the other a yorkie), and i have 1 male he's a yorkie/pomeranian
 
I do have to agree that they each have their own different personalities. I love all my kiddies! I got Oreo first, and he's just a doll! He's the sweetest little man ever.  
I do find it funny how Oreo will always be a momma's boy and Ginger will be a Daddy's Girl and My Maltese Cloey Loves both of us! Lol.. But i've heard that boy dogs will Be in love with you and Girl dogs will love you. or something like that  
 
  
I do like my girls because i get to dress them up, but i dress Oreo up as well in boy clothes so it's not all that bad  
 
  
But just get 1 of each! lol.. i'm looking for another boy so that way it'll be dead even lol  
 
  
with whatever gender you choose, best of luck!
