There's a show that an English lady does, similar to the Dog Whisperer, and she just dealt with this issue. Try looking on Animal Planet for it. I don't want to repeat what I remember because it might be incorrect... but I think it might be "fear aggression".

My Max was behaving badly on the leash too, but we took him to the doggy park and tried walking him on it there. It was terrible. Then another couple told us to let him off the leash so that the dogs could be on even ground (one restrained and the other not). It worked! Two times circling each other and the aggression was over! We have taken him walking around the neighborhood and he has done 99% better!

I think the problem was that he has only been around his sister since we got him, and he needed to be socialized more. Once the fear of what was going to happen was eliminated he came off that defensive mode.

Hope this helps...
