When we first had aggression problems with Pebbles the dog trainer suggested the vinegar and water in a bottle. She was so bad with the aggressive barking that we called her Devil Dog. The first time she was sprayed it was like an exorcism. After that first time all we needed to do was show the bottle and she would immediately stop. We don't even have to use it any longer.
So glad that it works for others as well!
