Well, the impressive “sliding stops” were usually the dead giveaway.
Never had a single soul “get a’skeered” of my dogs.
[but, as I mentioned earlier, I’m in Hillbilly World where people are made of tougher stuff]
People who "own" big dogs highly tend to have a good understanding of dog behavior and risks.
Some retards stole a fake, lighted wreath off the house a few weeks ago. Now if the dog barks, she is let out on her own at any time during the night while I load the shotgun. (The dog is black, so I can't see her at night, but perps are likely much more visible).
