With your tiny terror I would read up on the Nothing In Life Is Free type way of dealing with a territorial or dominant dog on Google and get her involved in positive-reinforcement behavior modification training that you can also read up on here on YT or on Google and do yourself at home. Sounds like she needs a leader in every area of her life and a job - get her working learning and using that energy and drive of hers for something good. She sounds insecure/aggressive and needs strong but loving, patient leadership that makes learning a fun game with bigtime rewards to get her redirected toward the positive side of life. You might use a soft muzzle on her while you are working on her behavior issues when children, etc. are around. If you go with a professional trainer, please use someone with some years on them and a good history you can verify and who carries their own insurance or your homeowners or canine liability insurance covers.

I don't know what Bark Busters is but I would keep this dog far from anything that shocked or buzzed or sprayed her in her state. Just some leadership, loving, fun training work and a new lease on life doing a job will likely help her far more than anything else.
