anyone have experience dealing with dog aggression?

Honestly, I only have 2 dogs, but I know exactly where your coming from. My year and a half old pitbull is VERY protective and possessive of me and she barked at EVERYTHING, yada yada. I've finally broke her for the most part, but if another dog gets in the yard or something, there not gonna get out alive most likely. She's as sweet as can be, but when a dog she doesn't know gets around her, its not gonna be pretty. For instance, I took her to the dog park, and I couldn't even let her loose. She tried to attack every dog that came near her and she even started foaming at the mouth. Funny thing was though, when I left her in the pen by her self, and walked off, she quit. Anyway, the barking is a pretty simple one usually. When they bark at something, bite her on the ear. Might sound strange, but I swear to God it works...
