"you kick my dog"

I ran over a dog yesterday.
That was weird.
The owner had the dog off it's leash and both of them were running across the street.
As a passed them the dog bolted backwards and I could feel a bump and heard a yelp.

The dog ran off, the owner ran after the dog, I sat in my car like "wtf just happened?"
"Do I sit here and wait for them to come back?"
"Should I attempt to follow them to make sure the dog is okay?"
"Should I leave a note on the ground?"

in the end I drove off.
Sorry little doggie.
Hope you are not dead.
Maybe you should get a better owner though.
just saying.
