Myotonic goats are also called Wooden Leg goats, “stiff leg” or Tennessee fainting goats. These are one of the few goats that are indigenous to the U.S. There are two strains of this animal. Most of those found in Tennessee and the eastern U.S. are smaller. When the goat is being fed or becomes startled its muscules become stiff allowing the goat to fall on the ground in a fainting position.
