True story for you south....when my first dog (a gentle little labrador with a big, nasty bark) was young, I used to go home at lunch to let her out to pee. While eating lunch in my suburban neighborhood with 2 income familie in the middle of the day, the doorbell rang. My puppy, who most likely would have licked the guy went berserk with barking....by the time I got to the front door, this guy was backing off the porch and getting ready to hit the highway. Were his intentions less than good? Nobody knows. But...without a single shot fired...or a single shell chambered, the "threat" to my home was taken care of. In my CURRENT house I have TWO 80 pound labs who lounge on the sofa in the living room (I'm single therefore the dogs own the living room) and they look out the front window. When someone is in the yard or driveway, they BOTH make a horrendous barking sound and the younger one has that badass raised hair on the neck look that I really don't think I need a gun. Combine that with the fact that the police station is less than a mile down my street...I feel pretty safe.
Of course, that doesn't protect me from government oppression,but then again, I'm not one who feels the government is out to get me
