The Jacob, although of unknown origin, has been raised for over 350 years in England. The Jacob is small and multihorned with black spots randomly distributed on the body and distinctive black facial markings over each eye and on the nose. They produce a medium-grade wool with some kempy fibers that create a hair effect characteristic of tweed clothing.
