I´m sorry that you lost your dog Kenny, losing a pet to traffic is ten times worse than losing them because of old age.
We had a old cat that got run over when I was five. That was on the dirt road to our house. We figured out that it was our neighbours wife who had done it. It was only her and the mailman that had driven on the road that day. She had probably been drunk that time, she often was and she usually drove way too fast on this little road. We didn´t talk to her anymore after that. And we werent suprised when they got divorced a few years later. Some people shouldn´t have a driverslicense at all.
