The Airedale Terrier, also known as the Waterside Terrier, the Yorkshire, the Bingley Terrier, the Warfedale Terrier, the Broken-haired Terrier and the Working Terrier, is a hardy, water-loving dog that is the largest of all terriers. Its name comes from a small otter-river, the Aire, in northern England. The Airedale is known for its extreme intelligence, dense wiry double coat, high energy level and tenacity. This breed is peaceful unless provoked; they are said not to pick a fight, but always to finish one. Airedales will fight furiously to protect home and family and typically are better with people than with other dogs. If not properly socialized and trained from a young age, Airedales may exercise their intense prey drive on smaller dogs and cats. Without regular exercise, they can become destructive. Male Airedale Terriers should be 23 to 24 inches in height and weigh between 50 and 65 pounds. Female Airedales should be 22 to 23 inches tall at the shoulder and between 40 and 45 pounds in weight. Fairly intensive grooming is a lifelong requirement to keep an Airedale’s coat and skin in good condition. They do not shed as much as many other dogs, but they do shed their entire coats twice a year. Acceptable coat colors are tan and black, and tan and grizzle. The Airedale was accepted into the American Kennel Club’s Terrier Group in 1888.
