A versatile American herding breed developed in California by Scottish immigrant Alexander McNab to work sheep and cattle.

Who is this breed suited to?

The McNab is worth considering for a home interested in stockdog work and willing to investigate documented lineage rather than rely on a visual identification.

Daily time commitment

Ask what an ordinary working day involves for this line and plan daily activity and training accordingly; a registry label is not an exercise prescription.

Coat and everyday care

See the parents' coat routine and check feet after demanding ground; a practical working coat still needs regular hands-on examination.

Challenges to plan for

The McNab foundation stresses records and broad genetic documentation. A resemblance to a short-coated collie is insufficient proof of ancestry or working ability.

How does it compare?

The Border Collie is a useful stockdog comparison, but McNab lineage and selection should be established separately rather than inferred from colour.

Questions to ask a breeder

What records support McNab ancestry and what work do close relatives perform? Can you show health results and describe early handling and stock exposure?
