This goat breed is called by its name due to its very stiff or tough legs. They are raised in US and some Texan ranchers even called it by a new name called Tennessee Meat Goats. They are also marketable as pets since they are very interesting and unique. When they get scared, they can lie down stiff and that would last for several seconds. No one has really discovered the roots of their origins. This breed is also considered as good mothers since they also produce a good amount of milk. They are already included in the rare list of the American Livestock Breed Conservancy.
