How to make my dog less anxious and protective?

It sounds like you have the right ideas, but need to spend more time actually training the positive ociations you are seeking. When you say you "correct" her for growling at dogs, but you don't mention how. After the trauma of being attacked, it may take a long time for your dog to feel confident again. The best way you can help is to avoid situations where she feels stressed or threatened. Arrange some meetups with a non-agressive dog, so that you can give your girl lots of positive reinforcement for NOT reacting negatively when approaching other dogs. Praise is great, but you have to move on to treats if you want to balance out the fear issue. I also suggest joining the Functional Rewards Yahoo group, which focuses on training for reactive dogs. The list owner is an amazing trainer, and the archives will teach you more than you need to know to help your girl recover!
