BORDER COLLIE. The workaholic of the dog world, the Border Collie is the world’s premier sheep herder, prized for its intelligence, extraordinary instinct and working ability. Medium-sized and athletic, the breed controls stock with stalking movement and an intense gaze known as "eye." In the border country between Scotland and England, Border Collies (first classified as the "Scotch Sheep Dog") were invaluable to shepherds by allowing them to maintain large flocks of sheep. The breed as we know it today has been around for more than 100 years. In the second half of the 19th century, Queen Victoria spotted a Border Collie and became an active enthusiast. At this point, the divergence between our modern Collie and the Border Collie began.
