Cairn Terriers are smart, alert, and confident, but they do have a classic terrier stubborn streak. They thrive with consistent, positive training and benefit from early socialization. Their high prey drive means a fenced yard or leash is a must.

Their shaggy double coat is weather-resistant and comes in many colors (except white). It requires weekly brushing and occasional hand-stripping to maintain texture and shape. Cairns shed minimally and are often considered allergy-friendly compared to other breeds.

The Cairn Terrier is one of the oldest terrier breeds, originally bred in the Scottish Highlands to hunt foxes and other vermin among the rocky cairns that gave the breed its name. Best known for its bold spirit and scruffy charm, the Cairn is famously tough for its size.

Compact, alert, and always up for an adventure, Cairns are intelligent and independent but also form strong bonds with their families. Despite their working roots, they adapt well to modern life—as long as they get enough mental and physical stimulation.
