Mc Nab - For over a century these dogs have been working sheep and cattle and are more popular than ever with ranchers. They are a native stockdog from Mendocino County, CA. via the Grampian Hills of Scotland. In 1868 Alexander Mc Nab came to the U.S. from Glasgow, Scotland. It was here he developed his line of Mc Nab shepherds from carefully selected Border Collies. These dogs are medium sized, alert and cat-footed. Their coat is black with white markings. Their are 2 types, long haired and short haired. The long haired Mc Nab is adapted to the severe winters of Scotland.
