Cairn Terriers 101

Terrier group

The Cairn Terrier, like other Scottish Terrier breeds, is a determined character that never backs down from a challenge. Developed to be vermin-hunters, they are not typically safe around small pets such as hamsters. They love their families and are playful and impish, but not particularly fond of strangers or other dogs.

Cairn Terrier coat care and colors

The wiry coat of the Cairn Terrier is one of the easier classic terrier coats to keep in shape. Regular brushing will help to remove any loose or damaged fur. While Cairns, like other small terriers, are traditionally and painstakingly "hand-stripped" of their outer coats, this is rarely done outside of the show world these days.

Cairn Terrier exercise & training

Exercise level

Exercise level

The Cairn Terrier is an active breed that will still hunt down any mice daring to show their faces in the house. These tough little dogs will take as much exercise as you can give them, but because of their short legs, they will be satisfied with long, brisk walks.

Trainability

Trainability

As with other small terriers, Cairns do not lack intelligence, but they prefer to do things their way, not yours. Get an early start on manners and socialization with positive training and boundary-setting. Teach good nail-trim behavior early to prevent future struggles.
