Which goat breed undergoes a temporary paralysis when frightened?

The breed of goat that undergoes temporary paralysis when frightened is the Myotonic goat, commonly known as the "fainting goat." When startled, these goats experience a genetic condition called myotonia congenita, which causes their muscles to stiffen and can lead to them falling over or becoming temporarily immobilized. This reaction is harmless and typically lasts only a few seconds. Despite this unique trait, Myotonic goats are known for their friendly temperament and are often kept as pets.
