Very true indeed. My experience is strictly anecdotal, but at night (and during the day), dogs watch over my livestock. I use Great Pyrenees dogs and while they are friendly to us, they get downright vicious to strangers around their charges. A joke is that if you drive by a field of sheep or cows and can't spot the dog, just park the car and walk up to the fence. The dog will come out from wherever he is and go NUTS!
Between rednecks, hunters, territorial property owners and dogs, farm hands, cops and Virginia's strict trespassing laws, I don't see how JM would risk it.
And if it is a horse farm, forget about it. He would have to be practically suicidal to trespass on a horse farm. I just can't shake the feeling that if he left her on private property, he knew that there werent the usual "security" measures in place and that the farm wasn't a working farm.
Edited to add: horses and roosters are excellent "guard dogs." they will let you know if anything is amiss in your fields.
Thanks for your post (I used to have a Great Pyrenees -- most beloved dog ever!). I agree that in a commercial farming or relatively sophisticated hobby farm, the security can be pretty tight, but I recently moved away from a small farm on 50 (largely wooded) acres (maybe 10-20 acres, tops, open) that was a couple miles off the main road. You had to drive down two long dirt roads to get to it, and practically nobody even knew there was a house tucked back on the river where I lived. The property actually had two houses (one belonging to the owner) and a bunch of outbuildings, and assorted equines (shetland ponies, donkeys, horses), goats, sheep, chickens and other fowl. I lived there for four years and always had the subjective experience that I knew when cars were coming down the driveway, because sometimes I heard them. However, it was rather shocking how often I found unexpected things, among them, a young pig that had been dumped about 200 yards from my house?!?, a stranger in a pickup down by the river who had brazenly driven all the way down the driveway and then down a
walking path to get there, an unexpected UPS guy suddenly within sight, etc. to realize that when the leaves were on the trees, you could not necessarily hear vehicles until they were within sight of the house, which means they could have been bumping along for over a mile before I knew they were there.
My house was only about 200 yards from the chicken pen, but it was a little hilly and a couple times I arrived at the pen to find that there had been predators during the night. I am sure that the roosters (we had two, one was a casualty) and chickens were making a lot of noise during the masacre, and I'm a light sleeper, but I managed to sleep right through it.
There were also nine dogs on the farm -- seven in one house, which was about a quarter mile from mine, and I had two. None were guard dogs, per se, and none of them were ever left in the pasture, but you would think that with nine dogs, we would always know when someone was on the way before someone was rumbling into sight. Nope. Also, they barked at so many things that it wasn't obvious that they were barking because someone was coming or if it was because they saw a particularly interesting squirrel (of course that would be less of a problem with a proper guard dog).
Anyway, I think many would be surprised at how easy it is to enter a large piece of land without being detected. I also know, from running around looking for one of our free-range birds that disappeared (a coyote casualty, I guess), and trying find the injured barn cat (who turned up in time to be taken to the vet...never did find where she had been hiding), that trying to find something in wooded terrain, even as little as 30 acres, can be an almost impossible task.
