[Cha Cha]

Over the years, I have had problems with female dogs in this manner. I believe these females are fighting over position in the pack (the whole family pack including humans). While one may be more submissive, the other sees her as a threat. The more submissive one likely does not start the fights, but she won't back down from one either, rather she will defend herself and her position in the pack. She likely will not win the fight either. These types of confrontations are very dangerous to you, and to the dogs as they will inflict injury to one another. They likely see you as the pack leader, (their source for basic needs..food...water) and these confrontations happen sponatneously when you enter the room, or are nearby, because they have an "order" in which they greet, or approach their leader, and when one breaks that order, stuff hits the fan! I have never had good luck with these situations other than seperating them when the aroma in the air is not right. If you watch them closely, you will start to see warning signs as to when a fight is about to break out. At that point, I seperate for a while. They have very specific body language that says they don't like what the other is doing. Can be a circling motion, hair standing up on their back, or even eye contact with one another. Others may have better ways of dealing with these situations, but spaying has never made a difference that I have noticed.
