Origin and history
Where the breed comes from
The Cairn Terrier originated in Scotland, specifically developed on the Isle of Skye. It is considered one of the oldest terrier breeds. The breed's name comes from its original use by farmers in the Scottish Highlands: they were employed to hunt and flush out foxes and vermin from rock piles known as cairns. The breed's history is tied to this working purpose, though specific dates of development are not provided. The Cairn Terrier was recognized by the American Kennel Club in 1913, but recognition status varies by other registries. The breed's shaggy, weather-resistant coat and small size were well-suited for navigating rocky terrain and burrowing after prey.
