This is a personal choice. The male is larger, showier and inclined to be more boisterous. The bitch is usually more maternal, somewhat smaller and much more inclined to be a homebody. My experience – and this is my opinion only – is that the females tend to be more affectionate and “in your lap” while you will find the males off sleeping somewhere. In my house, the females tend to do most of the “guarding” work while the males just watch and react only when they absolutely have to.
