I am sure that is true. However, I have watched my Great Pyr leap up out of a sound sleep with a huge deep bark when he hears the cat get up on the front porch. This from the other end of the house, upstairs, with the TV on watching a shoot 'em up. They have fantastic hearing and nothing gets by him. Especially at night when he is on guard. How he hears that is amazing. If I knock softly on the front door after dark he goes nuts and races to the door and explodes up against it with both front paws at about 6 feet up on the door, just a snarling. He's a great dog. There's stickers on each door and the windows that say there's a Great Pyrenees Mountain Dog on guard. They will know it's true long before they notice the stickers. Plus, me being a combat veteran, that first bark puts me at maximum pucker from the get go and i'm in kill or be killed mode before my feet hit the floor. As Mr. T used to say," I pity the fool that decides to break in to my home." Lest you think i'm bragging here, i'm not, just stating the facts. I have spent countless hours inside shooting houses of all kinds, both at night and in the day, with teams of badasses hunting me and mine, and have been the hunter as well. I rarely got taken by surprise, and was never captured in training. I have also taught this stuff to soldiers on their way to the sandbox. While a handgun is useful inside structures it is only as good as the shooter holding it. A rifle, such as my 30/30 lever action, is just as effective when used wisely. Pie cut those corners, get low, know where you can shoot through the walls, practice, practice, practice. Your average thief is not a Special Forces Veteran, but rather a crack or meth head looking for something to sell, or cash. Not a real great planner there and fairly easy to disarm, and scare the crap out of them. I know every inch of my home, in the dark, while they have entered it for the first time. Like most soldiers I have undergone many levels of Combatives training and target practice and like most if not all Aviators have gone through SERE 1 and 2. I have instructed escape and evasion courses while in the service. Granted, i'm almost 60 now. Not dead yet.
