At least where I live, Animal Control Officers are considered "cops" and go through the same training as the others, initially, and wear the same uniform. But I don't know about other areas... Where I live, if an officer is aggressively approached by a loose dog, it will be shot, especially if it is a pit-bull. The people who own them complain, but they have no case because the dog is loose and aggressive. It sounds like the Animal Control Officer is just trying to do her job... But they may get tired of the complaints eventually and quit responding to them, if there is repeatedly nothing to cite after they respond. It is unlikely that they are necessarily "out to get you" personally. When a complaint comes in, they have to respond, at least initially. Hopefully, you will get anymore personal threats from these people on a recording device (your cel phone?) and take that to the police. Make these neighbors come to you to do such things, you should stay away from them and off their property. That way, they can't say that they were provoked in any way, which would have prompted the threat.
