There aren't dogs at my end of the street - these dogs were from further away.

In both cases the doe never backed off an inch. Once close enough the dogs realized that the deer was BIG, was not running away, uh oh... the doe took off after the dog as soon as the dog changed direction, and the doe kept on the dog's tail at least until they were out of sight. Even a domesticated dog sure can run when motivated...

I have no idea if it was the same doe - we've got a bunch around here. In both cases my attention was on the dog as I first thought it was charging *me*, not realizing there was a doe some ways behind me until the dog's path was clearly missing me.

"Doe kills man" is not exactly a daily headline so I'm not that concerned, but it is a large animal that I actually encounter almost daily that could theoretically be dangerous, and it would be nice to understand what triggers the aggressive behavior... I assume the dogs triggered some newborn/baby defense reflex.
