Thanks for the replies,
First of all, I asked for help to stop her from running up to other DOGS, not people. Yes, I wrote that I dont have worries: worries from her running up to my neighbours who actually love her and dont mind. As I said, she stopped running up to strangers a while ago, she stops as I tell her to stop. But its not the same with DOGS.
I am keeping her leashed, and ofcourse I'm trying NOT to yell at her at all, thats why I'm asking for tips because I have no success yet and figured that more experienced people would able to help from their own experience in training (and not sending the dog to trainer).
Thanks anyway, didnt meant to be rude or something, maybe i wasnt clear enough.
