Breed History:

The Cairn Terrier originated in the Scottish Highlands and the Isle of Skye, where it was developed as one of Scotland's oldest working terrier breeds. For centuries, farmers and gamekeepers relied on these hardy dogs to hunt foxes, badgers, otters, and rodents hiding among stone cairns, from which the breed takes its name. Its small size, courage, and determination made it exceptionally effective at flushing out quarry from rocky terrain.

The breed remained a valued working terrier before gaining wider recognition during the early 20th century. Although still capable of performing its traditional hunting duties, the Cairn Terrier became increasingly popular as a cheerful and affectionate companion. The breed also gained worldwide fame through Terry, the Cairn Terrier that portrayed Toto in The Wizard of Oz.

Today, the Cairn Terrier is admired as a loyal family companion, capable working terrier, and spirited breed known for its intelligence, confidence, and cheerful personality.
