A collie is a distinctive type of herding dog, ultimately originating in Britain, especially in the upland areas of the north and west. 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.
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.
