Size and appearance

The Cairn Terrier has a harsh, weather-resistant outer coat that can be black, cream, wheaten, red, sandy, gray, or brindled. Pure black, black and tan, and white are not permitted by many kennel clubs. A notable characteristic of Cairns is that brindled Cairns frequently change colour throughout their lifetimes. It is not uncommon for a brindled Cairn to become progressively more black or silver as it ages. The Cairn is double-coated, with a soft, dense undercoat and a harsh outer coat. A well-groomed Cairn has a rough-and-ready appearance. Cairn Terriers tend to look similar to Norwich Terriers, but with some differences (for example the shaggy fur). The outer layer of fur is shaggy, but they have a soft, downy undercoat. The ideal height is roughly 28 - 31 cm, with weight in proportion, usually some 6 - 7.5 kg.

Exercise and activities

Care planning: build a weekly routine with walks, play and time to explore. Enter the minutes and sessions that work for your dog, then compare the weekly total with your available time. Keep notes about the activities your dog enjoys and adjust the routine together.

Training and enrichment

Care planning: choose one everyday skill to practice and keep a record of each session. Note the cue, the reward your dog enjoys and what went well. Rotate familiar games and new activities, and use your notes to choose the next small step.

Coat and grooming

Care planning: use the coat details above to discuss a grooming routine with your groomer. Record brushing sessions, baths and appointments in the app. Add the tools you use and your preferred schedule so the whole household can follow the same routine.

Breed history

Cairn Terriers originated in the Scottish Highlands and the Isle of Skye. Prior to 1873, terriers in Scotland were collectively referred to as 'Scottish Terriers'. In the early days of the breed's establishment, the name 'short haired Skye Terrier' was used. After concerns raised by the Skye Terrier Club, the name 'Cairn Terrier' was given to the breed instead. The name 'Cairn Terrier' comes from cairns, where the terriers often flushed out vermin. The Cairn Terrier was registered into the American Kennel Club in 1903. The Kennel Club of the United Kingdom gave the Cairn Terrier a separate register in 1912; the first year of recognition, 134 were registered, and the breed was given Championship status. While registration of white Cairns was once permitted, after 1917, the American Kennel Club required them to be registered as West Highland White Terriers. The dog was definitively accepted by the Fédération Cynologique Internationale in 1963.
