At a glanceThe Cairn Terrier is an active, hardy terrier with a weather-resistant double coat. Dogs Australia describes courage and self-confidence without aggression in its ideal.WORKING DOG reference library · Added 2026-10-19 · Editorial guideBreed identity and working backgroundSmall terriers are part of the working-dog story even when most local individuals are companions. A useful library keeps terrier function distinct from livestock gathering, guarding and gundog tasks. For a modern dog, describe documented activity rather than assigning a working status automatically. In historical content, source a particular regional or employment claim and preserve the original context. A breed can connect to rural culture without every member holding the same job.Temperament, build and coatThe Australian standard describes an active, game and hardy dog with an assertive, cheerful disposition. Its double coat combines a profuse harsh outer layer, which should not become coarse, and a short soft close undercoat. Slight wave is allowed. Practical care therefore requires more detail than a generic shaggy-coat label. Ask how adults are maintained, how they cooperate with handling and what activities their keepers use to provide suitable occupation.Living, training and choosing a dogAsk the breeder about adult behaviour, available screening records, early experience and ongoing support. Explain the other animals and ordinary situations the dog will encounter. Plan secure management and supervised introductions rather than assuming small size decides compatibility. For companion life, provide useful learning, appropriate activity and rest. If a sport interests you, check eligibility and instruction locally. Observe adults during ordinary routines to understand the family more clearly than a brief excited interaction or a photograph allows.Sources & further readingReferences for this guide.
