One time many years ago, my horse Cocoa and I were out trailriding in the woods, alone.
A pack of wild dogs came after us... I kicked her trying to get her to run, but instead, she spun around at the dogs chasing us and kept rearing up and flying her hooves at them. She hit a few of them and they all ran off except for the one, which she killed.
Horses/mules are pretty amazing animals
