Breaking up a dog fight when you're alone is much more difficult and daunting. It takes speed and swift movement and lots of adrenaline. Again, the goal is to break up the fight without getting hurt. If you can manage to stay calm and focus on the task on hand, you should be able to succeed before any real damage is done.
I can tell you screaming at the dogs to stop will only result in you having a sore throat. Remember that they are only focused on the fight, and like a boxer responding to the bell, they can't focus on what's happening around them. You'll need to grab a leash. Slide one end of the leash into the looped end and slip it under the dog's belly, towards the groin, creating a sling. Like the wheelbarrow, lift the dog and give a moment to allow the dogs to disengage - and very quickly but calmly, direct the dog away, preferably to another room or behind a fence. If the other dog is still coming for the anchored dog, step around to the rear of loose dog and use the wheelbarrow method to steer that dog in the opposite direction. The wheelbarrow is helpful in keeping your hands and arms away from their mouths, but still be aware of their heads. A highly stimulated dog may attempt to redirect on you.
