Our family has 2 huskies. They are from the same litter and both are female. They are about 5 months old. They fight horribly. It's not playing aggressively, it's just fighting. They've gone so far as to draw blood from each other. I can't seem to find a trigger and they have both started the fight at some point. They don't listen when I call them off which is weird because they're really good dogs and always come when called. I need advice because I have no clue where to go from here and I don't want them hurting each other.
