Cairn Terrier (Cairn)

Weighing 13–14 lb (5.9–6.4 kg) and standing 9–10 in (24.1–25.4 cm) tall, the Cairn Terrier is a small-sized representative of the Terrier Group. AKC registration statistics place it at #71 in popularity. The breed traces its roots to Scotland. As with most breeds, males occupy the top of the size range.

How long do Cairn Terriers live? Based on published breed data, a typical lifespan is 13–15 years. Lifespan is influenced by size, since smaller dogs generally outlive larger ones, alongside genetics, body weight, dental care and regular veterinary checkups. Keeping a Cairn Terrier lean, exercised and current on preventive care is the most practical way to reach the upper end of that range. For its size class this breed lands in the typical longevity band: neither notably fragile nor exceptionally long-lived.

Apartments can work with a solid exercise routine, though more space is preferable. The coat releases little hair, so lint rollers stay mostly idle. Low-maintenance coat: a quick weekly brush and the occasional bath cover it. No low-shedding claim applies here. Allergy sufferers should spend time with the breed before committing.

A balanced activity level — think one good walk and a play session most days. Most pick up basics readily but keep sessions short; boredom arrives quickly. Most do fine with respectful children, especially when raised together. Canine housemates generally work out fine, though same-sex pairs can need more management.

Every number on this page is meant to be used, not just read. The calculators below start from this breed's 6.2 kg average weight, which in our 152-breed database sits heavier than 18% of breeds, and turn it into daily food portions, crate sizing and first-year budget estimates. That percentile is not trivia. Food bills, gear sizing and medication dosing all track body weight. Data comes from the AKC breed profile cited below, and breed-specific health risks are exactly why comparing pet insurance early, while your dog is young and healthy, pays off.
