In temperament it is affectionate and loyal with its own people, steady, alert and quick to learn. It is often described as more reserved with strangers than the Pembroke and makes a watchful guard. Its name is often explained as Welsh for 'dwarf dog', though this origin is not certain.
The Cardigan is long and low, set on short, sturdy legs with fairly heavy bone, and its forefeet turn slightly outward. Its large, upright ears have gently rounded tips, and its long, bushy tail is carried low, much like a fox's brush. The weatherproof double coat is short to medium in length and comes in a wider range of colours than the Pembroke's, including blue merle, brindle, red, sable, and black with tan or brindle points, often with white markings.
The Cardigan Welsh Corgi takes its name from the old county of Cardiganshire, where small hill farmers relied on it to move their cattle. When common land was enclosed and the long drives to market declined in the nineteenth century, the breed lost much of its original work and became scarce. It remains uncommon today, and the Kennel Club lists it among its vulnerable native breeds.
