Depending on the size of the dog and the size of the car/truck, the person driving may not realize he hit anything. When I was 17, I owned what was known as a land yacht (76 olds 98), we had a little rat terrier that apparently got under the car and was sleeping. I backed over her head and didn't feel a thing, my parents showed up at the grocery store I was working at and informed me what had happened. I was in shock for probably 3 or 4 weeks.
I have also hit a dog that liked to chase tires, the only way I knew he tried to bite my tire and failed was the fact I seen him in the road in my rear view mirror. Yes, I turned around and knocked a few doors and found the owners.
And then there are stories like this... http://www.fox23.com/news/local/story/Man-Arrested-For-Beating-Another-Man-After/9YVnzgC8eEO7h1OY0lq0CQ.cspx
Sorry for your loss, though.
