20 mph highly unlikely. I posted on your other thread, what you need answers from the vet who did the "necropsy" which is what an autopsy is called on animals.

Is/was there evidence of skull weakness at the point of impact, which is I assume where the haemorraging occured? If yes what amount of force if you can estimate this would be necessary for an impact injury to cause bleeding? Secondly was their evidence of bruising, breaks, muscle tears on any of the toes of my Yorkie.

Lack of bruising given the time line you described might not be evident as death occured so quickly after injury. But muscle tears or ligamentous sprains would have evidence of injury.

I do hope your necropsy was a thorough one.
