I think you did pretty good. I wouldn't tap her nose, though, that can backfire and make her more agressive.
I would watch her as a person approaches, can you feel her getting tense or does she become very still right before she lashes out?
If yes, then that is when you need to do the correction, and be firm, as your voice has to interrupt her plan of attack. Use the same interuption each time, like 'Ah, ah!'. Don't use her name during the correction, ever. If you're sitting, move her off balance a little, away from you. A bench type seat would be great, you could put her off your lap and onto the seat.
Give treats to the people who will walk up to you. They can toss one to her if they are nervous. She will still learn that strangers have treats, and she will get them if she behaves.
Once you catch her before she lunges, she'll remember that (it may take 2-4 times depending on her level of aggression) and she may just look at you to see if you're paying attention. Correct her each and every time, Ah, Ah, then place her down and away from you. When she ignores the stranger, (she'll look away, and avoid eye contact), and is calm, end the correction with an 'Okay', provided she is calm, give her praise and a treat and she can get back on your lap. If she tenses up or goes right back into attack mode, do the correction again. Eventually she'll respond to just the voice interruption. Use that for anything you don't want her to do. |
