Have you guys ever tried to kick or hit a even a domestic dog that wasn't your pet? I have. They are fast. Even an average yard dog. Makes you feel like you are moving in slow motion as it easily moves out of the way. Maybe I'm just slow and uncoordinated but I have a hard time believing that a woman fights off a coyote and the fight lasts ten minutes.
Now, if it was rabid, had distemper or was otherwise sick, maybe a different story. But even a rabid animal, if not too far gone, remains agile and fast.
I had a patient who was attacked by a rabid fox. In her garage. She was an older lady and did finally fight it back long enough to get inside but that fox ate her up. Hands, legs, arms. I put a good many stitches in her. And a fox is maybe 1/3 the size of a coyote if that big.
Anyway, who knows. Maybe its all true. Fact can be even stranger than the media's incompetence.
