Border Collies came from the hills along the Anglo-Scottish border, where shepherds wanted dogs that could gather sheep with speed, focus and very little instruction. A dog named Old Hemp, born in Northumberland in 1893, set the quiet, intense working style the breed is known for. They're medium-sized and agile, usually 30 to 55 pounds, with rough or smooth double coats, most often black and white.
Many are quick, eager learners and bond closely with their people, though they can be reserved with strangers. That intelligence needs an outlet. Without daily exercise and mental challenges, a Border Collie may invent its own jobs, like herding children or chasing cars. Dogs vary, so each one's energy and sensitivity will differ, but plan on training, play and long outings.
