Breed History:

The McNab is an American herding breed developed in northern California during the late 19th century by Scottish rancher Alexander McNab. Seeking a hardworking and adaptable stock dog capable of handling the rugged terrain and harsh climate of the American West, McNab selectively bred herding dogs imported from Scotland with local working dogs.

The result was a highly intelligent, agile, and heat-tolerant herding dog known for exceptional stamina and livestock-handling ability. Unlike many show-oriented breeds, the McNab was bred almost entirely for working performance rather than appearance.

Today, the McNab remains highly respected among ranchers and active dog enthusiasts for its versatility, athleticism, and trainability.
