We have 15 dogs and 1 is a full male pit and we have a male Husky/Pit mix and a female Boxer/Pit mix and they are fine. Now I'm not going to tell you it's always roses because it's not. We have scuffles and only one major blow up and Smokey (our full male pit) was a bait dog for fighters. He was just neutered. One thing that you HAVE to do is establish that YOU are the alpha. We do feed Smokey in his crate, but that's only because he's aggressive due to the fact that he was starved. We always introduce our dogs on leashes first and the first show of aggression we jerk back on the leash and give a firm NO. I have to say that the bad reputation that Pits have is grossly over rated. They are the sweetest things around as long as they are treated well. They are no different than any other dog...it is all in how they are raised and unfortunately Pits are one of the main dogs of choice for fighting, so therefore they are branded as being bad dogs. You have to be a little more careful because of the way their jaws are set up, but other than that they aren't any different than any other dog. If I were you, I would insist to your roommate that Pork Chop be neutered...it makes a HUGE difference and it's also healthier for the dog....there is a far smaller chance of them getting certain kinds of cancer. Please don't give up and might I suggest that you see a professional trainer or at least talk to one to get some pointers. Please feel free to ask anything you want on here too.
