What functional classification describes the historical role of the West Highland White Terrier?

Answer

Earth-dogs

The West Highland White Terrier was developed historically in Scotland with the specific working background of hunting and dispatching small vermin. This function directly translates to its classification as an 'earth-dog.' This heritage instills inherent traits in the Westie lineage, such as tenacity, a strong prey drive, and natural tendencies toward behaviors like digging and barking, all associated with working below ground level to clear dens and tunnels of pests.
