Yeah, no hitting, it's not the most intelligent way to train any dog. We humans are the ones with big complex brains, there's better ways! I
did some classes with a trainer who advocated the hitting & jerking method of training. She had GSDs, even had obedience titles on more than one of her dogs, they were definitely "well trained."
Every single one of her dogs was somewhat hand shy, too. :( Her dogs seemed to lack spirit, they obeyed because they had to, not because it was enjoyable or rewarding...

I'd find a good basic obedience class - and not with the person who suggested the nose rapping.

Leave a leash on Josie, so you can correct her BEFORE she gets on the counters or whatever. Seems like right now she is almost making it a game, like saying "neener neener, so make me...!" :p
I remember that phase...seems I had to go back to the basics a bit with Cooper when he went through his snotty brat age.
