I had a run in with a pit bull a few years ago. I was driving home with the wife one evening when I turned the corner in my neighborhood and noticed a guy and two dogs. He was spinning around in circles while the two dogs did the same. I told the wife that the poor guy was having a heck of a time controlling his two dogs and I realized as I was saying that, that one of the dogs wasn't his. He had his old German Pointer on a leash, and it was winding around him while a pit bull was trying to latch onto the old dog. I told the wife that he was being attacked and I threw the car into park and jumped out. I ran over asking if the second dog was his and he said no, that it came out of nowhere and started attacking his dog. The pit bull got his dog by the throat and took it down as soon as I got to him. The guy was quite frankly, a big squish, and didn't know what to do- I was pissed this dog was doing this in my neighborhood and I wasn't about to just keep driving and not try to stop it. I've seen too many stories about dogs attacking kids in a neighborhood and it just made me mad. I grabbed the pit by the big spiked collar ( I wasn't sure if he would attack me or if he just wanted to kill the other dog) and tried kicking him in the gut. You can't get any leverage to put anything behind a kick when you're holding a dog by the collar. I started beating the pit on the top of his head as hard and as fast as I could. I hit him at least fifteen times as hard as I could, and it didn't faze him. Found out later it just broke my hand, but adrenaline keeps you going in the moment. I somehow thought about a report of a guy being dragged down by a shark and he got away by eye gouging the shark. I held onto the collar with one hand and took my right thumb and started grinding it into the eye socket of the pit. Once I got past his clenched eyelid and felt the eyeball, I pushed harder and ground his eye to pulp. That got his attention and he let the old dog go. As I tightly held his collar, I told the guy to get his dog the heck out of here. I had my wife call the police and I held onto him until they arrived. They said no crime happened cause a dog biting another dog wasn't a crime. They did take him for animal control to deal with.
