Protecting dogs and cats on the road.

I live near a busy street in the San Fernando Valley. It is sickening the way people speed and don't care if they hit a poor dog or cat. People have stopped in the past only to drag the poor injured, screaming dog onto the side of the road to get him out of the way. I believe that there should be a law that people must stop and get medical aid for the dogs and cats they have hit with their cars. At the very least they should stop and contact animal control. Many times people are killed by hit and run drivers and the drivers claim "Oh I thought I had only run over a dog." They run over people and don't stop because they think they can get away with the excuse "I thought it was only a dog." I believe that this law would not only help dogs and cats, but also help pedestrians who are getting killed by hit and run drivers all the time.
