===Appearance===
Collies are generally medium-sized dogs of about {{Convert|48|to|70|lb|abbr=on|order=flip}} and light to medium-boned. Cattle-herding types are stockier than sheep-herding types. The fur may be short,
or long, and the tail may be smooth, feathered, or bushy. In the 1800s, the occasional [[naturally bob-tailed]] dog would occur. The tail can be carried low with an upward swirl, or may be carried higher but never over the back. Each breed can vary in coloration, with the usual base colors being black, black-and-tan, red, red-and-tan, white with a colored head with it without other body coloration of sable, black and tan, blue merle, sable merle [[Coat (dog)|sable]]. They often have white along with the main color, usually under the belly and chest, over the shoulders, and on parts of the face and legs, but sometimes leaving only the head colored – or white may be absent (unusual) or limited to the chest and toes (as in the [[Australian Kelpie]]). [[Merle (coat colour in dogs)|Merle]] coloration may also be present over any of the other color combinations, even in landrace types. The most widespread patterns include sable, black and white, black and tan  and tricolour (black-and-tan and white).
