The Canaan Dog resembles none of the other herding breeds, arising from a completely different background. Nonetheless, this breed shares similar traits needed in any dog that must herd for hours. Canaans are medium-sized, square-proportioned dogs of moderate substance that combines strength, agility, and endurance. They are not exaggerated in any way. Their movement is athletic and graceful, with a brisk, ground-covering trot. They are able to change directions instantly. They have a double coat, with a short, soft undercoat that varies in density according to climate, and a straight, flat-lying, harsh outer coat, with a slight ruff. This breed can adapt to great extremes in weather ranging from hot days to cold nights.
