I have two spayed females that often fight like this. It started when we had to put down our older male dog, who was very dominant of the girls. When he left things got really disrupted for them, as I had a new puppy too. So they started fighting, sinc eboth of my dogs are smaller I can easily seperate them, and then hold them apart till they calm down, it's better for them to do it together in the same room if you can manage them, it's a dominance thing I guess, since only a more dominant dog can seperate them.
I don't normally deal with the whole dominance sort of issues, but with my dogs that was exactly what it was. So in turn I did a really firm NILIF(there's a sticky in the training section on it). My girls would even fight when I walked one of them inside from an outdoor training session, so I worked them hard around the door. Walking in and out, getting the other dog to stay a decent ways away.
