I like dogs. One of the neighbors has the best little Beagle I've ever seen, and she comes over to stay with us, for several hours a day, when they go to work.
However, I have NO love for big vicious dogs. A few years ago, a young couple moved into the area, and they had two of these pit bulls, and let them run loose. Those brutes liked to chase cars, and killed a couple of the young deer fawns. There were a couple of times they wandered into our woods and ran around me on the tractor...barking and growling.
Then, deer season came along, and one of the local hunters "took care" of these invaders.
If someone ever brought any of these into our area, again, I would probably carry a can of "wasp spray" with me and give them a good shot in the face, and if that didn't get their attention, I would become a "hunter".
