Fainting Goats in TN 1800s: Their origin ... traces back to the early 1800's when a farm worker appeared in Marshall, County, Tennessee, with three does and a buck that fainted. It was thought by his dress that he might have come from Nova Scotia. He was a quiet man and wouldn't talk to anyone so whatever he knew will remain a secret forever.
A myotonic goat, otherwise known as the fainting goat, is a domestic goat whose muscles freeze for roughly 10 seconds when the goat feels panic. Though painless, this generally results in the animal's collapsing on its side.
