The Collie is a large but lithe herder standing anywhere from 22 to 26 inches tall. The rough variety boasts one of the canine kingdom’s most impressively showy coats; the smooth coat’s charms are subtler but no less satisfying. Coat colors in both varieties are sable and white, tricolor, blue merle, or white. Collie fanciers take pride in their breed’s elegant wedge-shaped head, whose mobile ears and almond eyes convey a wide variety of expressions.Collies are famously fond of children and make wonderful family pets. These swift, athletic dogs thrive on companionship and regular exercise. With gentle training, they learn happily and rapidly. The Collie’s loyalty, intelligence, and sterling character are the stuff of legend. The majestic Collie, thanks to a hundred years as a pop-culture star, is among the world’s most recognizable and beloved dog breeds. The full-coated “rough” Collie is the more familiar variety, but there is also a sleek “smooth” Collie.
