I think you are going the wrong way about it. Animal control is weak sauce. Go whip your neighbors ass. That will fix the problem. I don't mean to sound like a tough guy... But sometimes it has to be done. I breed cl and xxl pitbulls. Never had a problem. All my dogs are gentle giants. If they aren't then I would take the necessary precautions to avoid things like this. Which your neighbor has failed to do.
