The history of the Cairn Terrier is enhanced by the fact that the modern Cairn is an attempt to preserve in typical form, the old time working terrier of the Isle of Skye. The fancier, for a proper appreciation of the Cairn, should know what the uses and appearance of these terriers were. Fortunately weights, engravings, measurements, descriptions of their appearance and accounts of the use of these terriers do exist.

From Martin's History of the Dog in 1845 and many additional publications from that time, it is plain that these were working terriers, with courage for the bolting of otter, foxes and other vermin from among rocks, cliffs and ledges on the wild shores of their misty isle.

Variation in appearance existed in these early times, as each breeder had his own fancies. But continued selection for a definite purpose soon resulted in the production of a rather definite type.

The Cairn's sporting instincts and vermin killing ability made him a useful member of the laird's and crofter's households. Becoming popular with those who desired a sporting terrier capable of hunting in all weather, he was taken up by fanciers and admitted to the English Kennel Club Stud Book as a recognized breed.

The head and the height of the Cairn terrier differs from all other terriers. Short and broad headed. His height, which differes from that of other terriers, is important in giving the breed its distinctive conformation - He is not so low to ground, and in proportion to his size, is slightly longer in the back than the Sealyham and the Scottish Terrier.

There is one, and only one, correct size for the Cairn Terrier, fourteen pounds for dogs, thirteen pounds for bitches, and the dogs should be in proper proportion to those weights.
