הקיירן טרייר הוא טרייר טיפוסי: בעל יכולת הסתגלות רבה, אך עם ביטחון עצמי מוצק. Despite its small size, the Cairn Terrier appears bold and sometimes downright dominant. At the same time, however, he is also very attached to his people and proves to be a happy and patient playmate with children. The Cairn Terrier adapts to life as a family dog and to single people and is also easy to keep.
