I went to look at a German Shepard pup once where the male dog was on the end of the chain trying to get a piece of me while the mother was crawling on my lap looking for affection.
I took that pup home and raised one of the best farm/guard dogs that I had ever seen.
Some people he would completely ignore while others would get the evil eye stare down.
And if you had a guilty conscience, you didn't get out of the car.
