Desensitization is usually the way to go with these types of fear aggression. Find a friendly Airedale and a cooperative owner and gradually desensitize your dog. I highly recommend The Cautious Canine by Patricia McConnell because it gives you clear step-by-step instructions with full detail and explanations. It also gives you some troubleshooting tips, but I'll try to sum it up. Basically, the whole jist of it is that you want your dog to associate Airedales with positive things, a.k.a. positive reinforcement.

Stand about 15 feet away or as close as you can be without getting a reaction from your dog. Then give her a command like "Sit" and treat her, praise her, etc. If she's responding well, walk closer to the Airedale moving at about 1-2 ft increments. Always check out her comfort level. If she starts to show the least bit of aggression or anxiety (quick panting, drooling, hair raising, anxious jerks on the lead, not responding, etc.), move back. The worst thing you can do now is to rush her. You may never get to a 5 ft distance from the Airedale until weeks from now, but that's okay. Then, again, you might make it in one session. Move at her pace. I know this sounds incredibly time consuming, but it's completely worth it. In aggression cases, it's *always* better to be safe than sorry. Good luck
