i guess senorita wil have no trouble since it´s a puppy, maternal instincts kick in, and iwht Face i see no problem, until maybe the pup is old enough to be considered competition, but maybe by then they are great pals, who knows, i never owned two males at same time, just females some are great but there are cases when they are not, it´s like flipping a coin, basing on socialization, training and jerarqui (sp?).
