Breed of terrier developed in Scotland to rout animals that prey on game.
The modern breed's characteristics are carefully patterned on those of the dog's ancestor, a 17th-century terrier of the Isle of Skye. This short-legged dog has a short, broad face. Its coarse coat is usually bluish gray, tan, or pale yellowish brown. Generally active, hardy, alert, and spirited, it is valued as a pet and watchdog. It stands 9–10 in. (23–25.5 cm) high and weighs about 13–14 lbs (6–6.5 kg).
