It's that the weirdest feeling ever when someone does that? When my female Doberman was alive I had a guy drive by us twice and on the third drive by he stopped and did the same thing. I told him that she was not within the breed standard and that I had her spayed when she was six months old. He looked at me like I was speaking another language, so I started asking him how often he showed his dobbie and what titles he won. Of course, he didn't show his dog, so I ask him if he had the dog's hips certified and if he knew about the life span of the parents. There was no testing so I told him that he shouldn't be breeding as his dog could produce puppies that would have a life time of health issues. He drove off calling me a few nasty names, but I can live with that
