Appearance
The Cardigan is a long, low dog with upright ears and a fox-like appearance. The old American Kennel Club standard called it an "Alsatian on short legs". Unlike Pembroke Corgis, who are bred to have only a small nub of a tail (without docking) the Cardigan's tail is long.
Size
An average Cardigan is around 10-13 inches (25-33 cm) tall at the withers and weighs from 25-35 pounds (11-16 kg).
Coat and Color
Cardigans can be any shade of red, sable, or brindle. They can also be black with or without tan brindle, or blue merle with or without tan or brindle points. They usually have white on their neck, chest, legs, muzzle, underside, tip of the tail, and as a blaze on the head. Other markings include ticking on the legs and muzzle, smutty muzzles, monk's hoods, and others. A few other unofficial colors can occur, such as red merle.
