The McNab Dog - commonly called McNab Shepherd or McNab Collie - is a herding dog that originated in the Mendocino region of Northern California. The McNab was bred to withstand the tough conditions found in California such as heat, burrs, foxtails, and rugged terrain. Until recently, the McNab was little known outside California, but the last three decades have seen a gain in popularity and geographic dispersal of the breed.
The McNab Dog is bred for its working ability and is not recognized by the American Kennel Club (AKC). For this reason, the appearance of the McNab can vary considerably. The dog is medium sized with females standing 16-21 inches at the shoulder and weighing 30-50 pounds and males standing 18-25 inches at the shoulder and weighing 35-65 pounds. The dogs have a variety of ear sets from pricked ears to floppy ears and everything in between. Most McNabs are black or brown with white feet, white collars, white facial strips and white tipped tails, but tricolor McNabs are well known as well as mostly black McNabs. Some McNabs sport random white patches on their bodies and faces. Their eyes are set well apart, almond shaped, and brown, hazel, or copper colored with occasional marble flecked or powder blue eyes. The McNab coat is close, dense and weather resistant. They can have a slick single short coat, a short double coat, or a medium length single coat, but their fur is never long. One of the distinctive features of the McNab is their cat-like feet which contribute to their agility. Another distinctive trait of the McNab is that it lacks dew claws on the rear feet, as opposed to the Border Collie where this is a common occurrence (per Gary Williams).
McNabs have a loose-eyed herding style and tend to work more independently than many herding breeds. They are skilled at both heading and heeling stock, meaning they can turn stock from the front or get behind stock and drive them forward. Originally bred to herd sheep, stock handlers quickly discovered that the McNabs bold nature and working abilities made them ideal for herding cattle. McNabs are also used for herding geese, goats, llamas and gathering horses in from the pasture. Renowned for their incredible endurance, McNabs have been known to cover over a hundred miles a day driving their herds.
McNabs often bond tightly to their family members, including other household pets. They have a keen sense of territory and seldom wander away from home. They are also more likely to defend their territory and family members than many of the more sensitive herding breeds. McNabs can be assertive and demanding, and they do best with guardians who are firm, consistent and skilled in positive dog training methods that don't trigger the McNabs instinct to push back against obstacles. Highly intelligent and quick to learn, the McNab needs mental stimulation as much as physical exercise. Families considering a McNab for a pet will need to set aside plenty of time to spend with their dog.
McNabs are hardy dogs with no breed specific health problems. Their average life span is 13–15 years. However, it must be noted that McNab dogs may carry the MDR1 mutant gene and can be very sensitive to Ivermectin, which is a common ingredient in heartworm prevention medications. This drug and others drugs can cause serious health problems and even death.
According to Washington State University, College of Veterinary Medicine: "Approximately three of every four Collies in the United States have the mutant MDR1 gene...The only way to know if an individual dog has the mutant MDR1 gene is to have the dog tested...McNabs have a 30% frequency". http://vcpl.vetmed.wsu.edu/
McNabs are becoming increasingly popular in the world of dog sports. Their outstanding athletic prowess and agility coupled with high intelligence make them ideal competitors. McNabs are now competing successfully in agility trials, dock diving, disc dog competitions, and flyball. They are also exceptional competitors in barn hunt and nose work. Many ranchers are competing with McNabs in the relatively new sport of Ranch Dog Herding where dog and handler on horseback work as a team herding three head of cattle through five obstacles and then into a stock trailer.
The McNabs reputation as an indefatigable "all-weather" dog is also opening up a new avenue of work for the dog: Search and Rescue. Currently McNabs are working as evidence search dogs, cadaver dogs, archaeology dogs, and area search dogs for missing persons. Where many other breeds have to be pulled off the search because the dog is tiring, the only limitation for the McNab is the energy of its handler.
In addition to the above activities, McNabs are now becoming more common as service dogs, demonstrating sensitivity to the medical and psychological needs of humans.
The McNab was developed by Alexander McNab in the late 19th century after he left his native Scotland and bought a 10,000 acre sheep ranch in the Mendocino region of Northern California. Looking to develop a herding dog that could handle the rough conditions on his ranch, McNab crossed the Scottish Collies he brought with him with the tough dogs of the nomadic Basque sheepherders he met near his ranch. Over time, the McNab dogs proved to be supreme herding dogs which California ranchers came to depend on with confidence. Now the breed is spreading across the United States and Canada with a few McNabs working as stock dogs in Germany and some sporting McNabs as far away as Japan.
