What specific physical traits were deliberately selected for when breeding the Westie for its role in the Scottish Highlands?

Answer

A hard, harsh white coat and a compact structure.

The physical characteristics of the West Highland White Terrier were rigorously selected to suit its original function in the rugged terrain of the Scottish West Highlands. The hard, harsh texture of the white coat provided protection against rough undergrowth and damp conditions, while the compact structure allowed the dog to maneuver effectively within the tight confines of underground dens, enabling it to successfully hunt and dispatch vermin such as badgers and foxes.
