Ok.
This happened today, I've been whirling it over in my mind. So I'm going to write it down to make sense (if that;s the right word)
Driving today behind a car , there was a dog, smallish , terrier type, prancing about in the back. The window was a bit open, it kept poking it's nose out.
I was a bit behind the car because I wasn't familiar with the road.
No idea how, but maybe the driver opened the window or the dog stepped on the window button but...........it jumped out.
The car coming towards it had no chance to avoid him.
I slammed on my brakes so I didn't rearend the car in front.
The noise. Oh the noise 
The whump of the car hitting the dog, it's howl 
I felt so sorry for the driver who hit it, you don;t expect that do you.
And the owner who had to lift his lifeless pet off the road.
And that little dog who was put in that situation.
And truth be known, me, who saw it .
I gave my number to both parties , but left them to sort it out basically. Don't know if there was any damage to the car.
Small conce=olation, it was quick
