Description of a McNab.

The breed has its roots in northern California, where they were first bred by a Scotsman named Alexander McNab. In 1885 McNab brought two Border Collies from Grampian Hills of Scotland to the McNab ranch in Mendocino County. These two dogs were bred to select shepherd females of Spanish origin which were brought to this country by the Basque sheep herders, and that cross was called McNab shepherds because Mr. McNab perfected this breed of stock dogs which would head or heel.
