The Border Collie is a herding dog breed developed in the English-Scottish border region for herding livestock, especially sheep. Ranked number one in Stanley Coren's The Intelligence of Dogs and typically extremely energetic, acrobatic, smart and athletic, they frequently compete with great success in dog sports, in addition to their success in sheepdog trials and are often cited as the most intelligent of all dogs. In January 2011, a Border Collie was reported to have learned 1,022 words and acts consequently to human citation of those words. The Border Collie is descended from landrace collies, a type found widely in the British Isles. The name for the breed came from its probable place of origin along the Anglo-Scottish border. Mention of the "Collie" or "Colley" type first appeared toward the end of the 19th century, although the word "collie" is older than this and has its origin in the Scots language.
