Temperament & character

The Cairn Terrier is bold, lively, and self-assured, with a pronounced hunting and digging drive rooted in its history as a fox and badger hunter. It is affectionate toward its family but independent-minded.

Exercise & stimulation

Exercise needs are high; varied daily activity involving scent and search work suits its original purpose well. Off-leash time should only take place in securely fenced areas because of its strong hunting drive.

Grooming

The harsh, wiry coat needs regular hand-stripping to maintain its texture, along with weekly brushing. The ears should be checked regularly because of the dense coat.

Suitable for beginners?

Only conditionally suitable for beginners, since the pronounced hunting and digging drive requires consistent training. Those who accept an active terrier temperament along with stubbornness will find a robust, adaptable companion.

Health & common problems

Breed-typical conditions include patellar luxation and craniomandibular osteopathy (CMO), a benign jaw-bone condition in young dogs. Genetic testing for von Willebrand disease is recommended for breeding.

Good with: Active families with a securely fenced garden
