Collie.-

This article is about the collie group of dog breeds and landraces. For other uses of the word "collie", see Collie (disambiguation).

For the Rough Collie, Smooth Collie and Border Collie see their separate.

The collie is a distinctive type of herding dog, including many related landraces and formal breeds. It originates in Scotland and Northern England. It is a medium-sized, fairly lightly-built dog with a pointed snout, and many types have a distinctive white pattern over the shoulders. Collies are very active and agile, and most types have a very strong herding instinct. The collie type has spread through many parts of the world (especially Australia and North America) and has diversified into many varieties, sometimes with mixture from other dog types. Some of the collie types have remained as working dogs, used for herding cattle, sheep and other livestock, while others are kept as pets, show dogs or for dog sports, in which they display great agility, stamina and trainability.

Common use of the name "collie" in some areas is limited largely to certain breeds – such as to the Rough Collie in parts of the United States, or to the Border Collie in many rural parts of Great Britain. Many collie types do not actually include "collie" in their name.

Appearance

Collies are generally medium-sized dogs of about 10 to 25 kg (22 to 55 lb), fairly lightly built with a pointed snout and erect or partly erect ears, giving a foxy impression. Cattle-herding types tend to be rather more stocky. Collies are always alert and are active and agile. The fur may be short, flat, or long, and the tail may be smooth, feathered, or bushy. Most types have a full tail, but some were traditionally docked, and some are naturally bobtailed or even tail-less. Types vary in colouration, with the usual base colours being black, black-and-tan, red, red-and-tan, or sable. Many types 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 coloured – or white may be absent or limited to the chest and toes (as in the Australian Kelpie). Merlecolouration may also be present over any of the other colour combinations, even in landrace types. The most widespread patterns in many types are black-and-white or tricolour (black-and-tan and white).
