Mcnab
The McNab is a California ranch dog developed for stock work, commonly linked to Scottish collie ancestry brought into Mendocino County by Alexander McNab and later working selection. It is usually a medium-sized, athletic dog with a short or moderate coat, quick reactions, and a practical style suited to cattle, sheep, and rugged ranch country. The breed is valued more for useful ability than for a single ornamental look.
A McNab needs work for its mind as much as exercise for its body. Herding, ranch chores, agility, scent games, and precise training can all suit the breed when handled fairly. Without direction, the same speed and intensity may turn into chasing, barking, or restless behavior. Owners should ask breeders about working style, biddability, grip, health screening, and family temperament, since ranch-bred lines can differ from sport or companion placements.
