So my room mate has this dog (some sort of pit bull mix) he found from god knows where, and it acts like it's been abused. I've been doing what I could to be nice to it, and I play with his ass every time I'm there. But tonight he kept getting off the leash my room mate keeps him on, and he followed me all the way to Cherokee street, and nearly ran into traffic.

So we drive back to the house to put the dog on the leash, but because my dumb ass room mate keeps bringing him in the house, the dog doesn't want to go back to his leash. So as I'm leading him by the collar towards the yard, and he growls, goes limp, rolls over, bears his teeth, and starts trying to bite me.

Because he rolled onto his back to bite me, my hand is now stuck under his collar, where he has a perfectly good chance to bite me. And bite me he does, he bites down just behind my thumb on the meat on my hand and starts shaking his head like dogs do when they're trying to tear **** to pieces. So with my other hand I grab his neck, so he cant jerk his head around while he's biting me. I try to just pull my hand out of his mouth, but the dog growls, and bites down even harder.

Now I was already pretty mad about being bitten by a ****ing dog that shouldn't even be living on the property, but after he bit down the second time, and started trying to **** my hand up some more I took action. The first kick was a medium strength, warning shot to the dogs ribs; which causes the dog to get an even better grip. Animal loves I apologize for my next actions but I felt they were justified. Since all peaceful negotiations, for the release of my damned hand from the pit bulls jaws failed, and no one had come to my aid; I used my free hand to place his head on the ground, and proceeded to kick the dog as hard as I could in the side of his skull. After the second full on soccer kick to the side of his head, the dog let go, began whimpering, **** all over himself, and proceeded to run and hide.

So what do you guys think? Am I a bad person for kicking my room mates dog in the side of the head as hard as I could, or is my room mate a ****, for bringing a mentally ****ed up, unpredictable pit bull to the house? Were my actions justified?
