My GSD was attacked. Now scared of everything?

I would check out nat geo wild and watch ceaser Millan the dog whisper. I've seen episode where this has happened and he lends his knowledge to put the dogs on the road to recovery. I no what ceaser say but I wish these dogs were not allowed in society they are just to dangerous. Whenever I see them when I have my dog I'm on gaurd. Hope your gsd can recover and return to her work. All the best
