Max is protective and is affectionate- a big big mush with his family. Our female is just a mush of mush and very affectionate and super super sweet - with her family. No stranger would think that as she watches over her property. They all have different personalities. Our working line was trained in protection he was not affectionate but he was not raised by us as a pup and I think that had much to do with it. Some dogs are more aloof then others. I agree ask the breeder what you are looking for and you will most likely get the right match.
