You're out on your farm, in a large field, alone, and you see an unfamiliar dog on your land. The dog does not wag its tail, put its head down, grin or smile, growl or put its hackles up. Its tail is in a half up half down position, motionless. It stands still, and then starts coming toward you at a brisk walk, with its head up, and its mouth closed. It does not show any teeth or growl or bark. It makes eye contact with you. The dog is about 140 lbs, about 36 inches at the shoulder, powerfully built, heavily coated, and is of a breed that you are not familiar with. You have read the newspaper for the area and you recall that a dog of this description was involved in a reported human bite incident a few houses down from you. Perhaps you might say, 'go home, git! Go on, git!' and the dog continues to come toward you (perhaps you wouldn't speak to the dog, please include if you would speak to the dog and how). There is now about eight or ten feet of distance between you and the dog and the dog is continuing to move in a straight line toward you at a steady gait. What would you do? Please folks, no arguing or cutting down anyone's response. I'm looking for a wide range of reactions and will not endorse nor disagree with any response. Please draw on your experience with dogs and your ideas about this dog's presentation to you, and what you should do. THis came out of a girl's night out chat we had a few months back. I was amazed at the variety of responses, but everyone except for me wasn't involved in dog training or rehab - I know many people here are, so what would you do.
