Borders are athletic, medium-sized herders standing 18 to 22 inches at the shoulder. The overall look is that of a muscular but nimble worker unspoiled by passing fads. Both the rough coat and the smooth coat come in a variety of colors and patterns.The almond eyes are the focus of an intelligent expression—an intense gaze, the Border’s famous “herding eye”, is a breed hallmark. On the move, Borders are among the canine kingdom’s most agile, balanced, and durable citizens.The intelligence, athleticism, and trainability of Borders have a perfect outlet in agility training. Having a job to perform, like agility—or herding or obedience work—is key to Border happiness. Amiable among friends, they may be reserved with strangers. A remarkably bright workaholic, the Border Collie is an amazing dog—maybe a bit too amazing for owners without the time, energy, or means to keep it occupied. These energetic dogs will settle down for cuddle time when the workday is done.
