isn't the reason most of us have more than one yorkie is that we wanted them to have playmates? my females usually are pretty well behaved unles one is in heat or pregnant they become a little more aggressive but separating them even for alittle while is enough for me to calm them down.when i leave them alone i don't have any qualms, they get upste being separated from each other so i would feel bad .but i could see if it was that out of control and you felt fearful to leave them together alone then definatly separate them |
