• I think we all have an idea of what alpha implies.  She demands other dogs submit to her.  She is more protective of food, bedding, objects that the male.  If you were to give the male attention instead of her, she would attack the male, similar to an alpha male great pyrenees that I owned several years back.  She is a usurper in that if fed in the company of other dogs she will consume her portion then chase the other dogs away from their food and eat it or at least prevent them from gaining access to it.  She is a pack leader and will correct other dogs that she perceives as displaying inappropriate aggression.
