The Border Collie is a working and herding dog breed developed in the Anglo-Scottish border region for herding livestock, especially sheep. It was specifically bred for intelligence and obedience. 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. It is also thought that the word ‘collie’ comes from the old Celtic word for useful.
Border Collies require considerable daily physical exercise and mental stimulation. Due to their working heritage, Border Collies are very demanding, playful, and energetic. They are better off in households that can provide them with plenty of play and exercise, either with humans or other dogs.
