Border Collies come from the hills along the Anglo-Scottish border, where shepherds relied on them to gather sheep with speed and an intense stare known as "eye." A dog named Old Hemp, born in Northumberland in 1893, set the quiet working style the breed still carries. They're medium-sized, usually 30 to 55 pounds, with rough or smooth double coats, most often black and white.
That working history explains the personality. Many are quick, sensitive and closely attached to their people, and most need a job to stay settled, whether that's agility, trick training or structured games. Without enough to do, a Border Collie may herd children, bikes or cars. Seasonal coat blowouts mean regular brushing, and each dog's energy and temperament vary.
