Take her to classes. Do not let other dogs come right up to her (protect her). This is just to get her used to minding you and ignoring other dogs. It will take some patience, but continue to go, redirect her when she starts to go off, have her focus on you, use treats. Treat for managing the LOOK or WATCH, for listening to you when you give her a command like SIT or DOWN. No treat for barking or not paying attention. After she gets a little more comfortable, make her work for the treat. LOOK, "good" SIT, "good sit" treat now; Look, good, Sit, good, Down, good-treat.
Pretty soon she should start getting used to the idea that she can get treats if she pays attention to you, and she will pay less attention to the other dogs. Do not let the other dogs get to her though.
