They are all different. I have a female and if you held her you'd say "Oh, I definetly want a female!". Then if I pried her from you and gave you my male to hold you would say "Oh my gosh, I though I wanted a female, but now I want a male! Ohhhhh, I just don't know anymore!!!!"
It will probably be determinee by how a particular puppy makes you feel
We had company....the woman said "Oh, I want one, but is has to be JUST LIKE THIS ONE!"
