Vital Statistics, Health & Life Expectancy
After The Wizard of Oz made the dog who played Toto into a star, there was simply no stopping this breed's appeal. But the Cairn Terrier's history dates to far beyond the 1939 classic--in fact, Cairns first appeared during the Middle Ages in Great Britain. Prized for their upbeat, merry, mischievous temperament, these enchanting little dogs grow to about 28 to 31cm (11 to 12 inches) in height and 6 to 7.5kg (14 to 16 pounds). With proper care, healthy Cairns can live to about 14 years.

Personality
These cheerful little dogs generally have curious, outgoing natures. Like many terriers, however, they can display an independent streak, and may require extra patience during training. Still, Cairn Terriers are highly intelligent animals, and extra efforts on the part of owners are likely to pay big dividends. While usually good with children, some Cairns may not get on well with other animals or strangers; however, this natural wariness is part of what makes them good watchdogs.

Grooming and Exercise
Cairns' shaggy, water-repellant double-coats require little grooming, but they do need to be brushed and combed at least once a week and bathed at least once a month. Owners should also check their ears regularly and remove dirt as necessary. Cairn Terriers need plenty of exercise, and should be taken on long walks or allowed to play in fenced areas whenever possible. Bear in mind though, that like any terrier, Cairns like to dig, so if you're planning to make one a member of your family, be sure your yard accommodates this behaviour.
