At a glanceThe West Highland White Terrier is a small working-terrier breed with a harsh outer coat and soft close undercoat. Its standard describes alertness, courage and friendliness.WORKING DOG reference library · Added 2026-10-19 · Editorial guideBreed identity and working backgroundThe Westie belongs in terrier working history alongside its familiar companion role. A white coat and small outline should not erase that functional background or be used to invent contemporary farm employment. A modern profile can accurately describe companionship, exhibition or sport while historical accounts retain their own dates and sources. Keep complete breed names and registration information where known. Appearance is useful for discovery, but a photograph alone cannot establish ancestry or a particular working qualification.Temperament, build and coatDogs Australia describes activity, hardiness and a self-reliant but friendly temperament, with alertness and courage. The double coat has harsh outer hair without curls and a short, soft close undercoat. Ask an experienced keeper to explain maintenance rather than assuming a pale fluffy presentation is the intended coat texture. Watch adults during ordinary grooming, handling and outings. The written ideal provides a starting point for questions, while individual behaviour and family routines provide evidence for a placement.Living, training and choosing a dogDiscuss your household, other animals and routine with the breeder. Ask about available screening documentation, early experience and support. Plan secure management and appropriate supervision rather than assuming small size guarantees compatibility. For an organised activity, identify relevant instruction and entry requirements. For companionship, include useful teaching, suitable occupation and opportunities to rest. Compare actual families and individuals instead of choosing only a recognisable face, a colour or a broad terrier energy score.Sources & further readingReferences for this guide.
