Actually, in cases where the dog is not intent on killing you, just trying to scare you, running is the worst thing you can do, because it will show fear. This could incite the hunter instinct in the dog, making the situation worse. If you back away slowly, in most cases the dog will not follow you. Showing fear to a dog is one of the worst things you can do. Unless you can run faster than the dog, which is unlikely, try not to just run all out away from it.
