I have 2 males n' 1 female. Asia(female) is very dominate....than Alex laid back n' the puppy is just there havin fun not worried about whos dominate or not. We have always had females all our life....GSD's...n' they are always very territorial. Then when we got Alex...he was more laid back not really worried. I guess I like both....so I guess I go after personality n' looks.
