I ran a bunny over before :( it ran from under a car and I didn't have time to stop. I felt so bad afterwards! I have also witnessed a golden retriever get slammed by a truck. It still haunts me to this day. The dude drug the body off the road and sped away. I gave police the description of the car(we were on vacation in VA), my sister got the tag off the dog since blood and guts don't bother her. We called the owner for two days to tell them. No one ever answered or returned the call. :( we had to leave that Sunday so we buried the collar as a "funeral". It was a sad vacation.
