His size, strength, and unflagging spirit have earned the Airedale Terrier the nickname 'The King of Terriers.' The Airedale stands among the world's most versatile dog breeds and has distinguished himself as hunter, athlete, and companion. The Airedale Terrier is the largest of all terrier breeds. Males stand about 23 inches at the shoulder, females a little less. The dense, wiry coat is tan with black markings. Long, muscular legs give Airedales a regal lift in their bearing, and the long head with its sporty beard and mustache, dark eyes, and neatly folded ears conveys a keen intelligence. Airedales are the very picture of an alert and willing terrier only bigger. Like his smaller cousins in the terrier family, he can be bold, determined, and stubborn. Airedales are docile and patient with kids but won't back down when protecting hearth and home. Thanks to their famous do-it-all attitude, Airedales excel in all kinds of sports and family activities.
