If you have to stay where you are, there are a bunch of things that you can do to make yourself less likely to be a victim. A bigger meaner dog is an excellent idea. 2 would be better. Also if you are willing to do it, you can buy a gun and teach her to use it. Get something that is effective but simple and not too intimidating. If you are not "into" guns there are other options that are also available. Look into these things too. But moving someplace safer is also a great idea too. It's pretty peaceful here in the Ozarks. Beautiful scenery and really nice people, C'mon down, my wife will fry ya some chicken and I'll buy ya a beer.
