Aly, I don't think what I do is that negative like you say prong training is. I certainly don't have the experience you do, so I don't know if I should say anything lol.

I do know that if the dog does something you don't want, you give them a pop (doesn't have to be hard..just enough for the situation you're in) Lets say, the dog isn't heeling, he's walking ahead...Most times I say "Noo" and my dogs will come right back into heeling without a pop, but if they don't, a little pop will do it. Then tell them heel again (to re enforce) and tell them how good they are.

With Josie's aggression, if she walks nicely by a dog, she gets a huge reward for it. It's soemthing she is still learning and it's VERY good if she doesn't growl..so, she needs a reward to make it worth her not to bark. Maybe a treat, or playing ball. So, if you think about it, the dogs are being told what they can't do by a pop, and being rewarded when they DO it right. So, the way I see it, the dog will learn rather quickly what he needs to do to get that great reward.
