Border collie or Border sheepdog is widely considered the most intelligent of all canids. They are working， herding dogs， originating from a wide swath of the England-Scotland border.
The Border collie is a breed of herding dog that originated in the Anglo-Scottish border regionFor a century， "collie" or "colley" was the Scots and Northern English word for a sheepdog， regardless of type. Collie is derived from the dialect expression "coaly"， meaning "black"， as in the coal mine; the word was subsequently assumed to be a color term rather than a reference to coal. The addition of Border in this breed's name refers to the location of the breed's development—the Anglo-Scots border. It was not until the 20th century that the word "collie" was used to describe a particular breed of dog.
