The Airedale Terrier (often shortened to "Airedale") is a terrier dog breed originating from Airedale in Yorkshire, England. It is sometimes called the "King of Terriers" because it is the largest of the terrier breeds, 50 to 70 pounds (23-32 kg). The breed has also been called the Waterside Terrier, because it was bred originally to hunt otters.
Airedale, a valley (dale) in the West Riding of Yorkshire, was the birthplace of the breed. In the mid-19th Century, working class people created the Airedale Terrier by crossing the old English rough-coated Black and Tan Terrier with the Otterhound. In 1886, the Kennel Club of England formally recognised the Airedale Terrier breed.
Well-to-do hunters of the era were typically accompanied by pack of hounds and several terriers, often running them both together. The hounds would scent and pursue the quarry and the terriers would "go to ground" or enter into the quarry's burrow and make the kill. Terriers were often the sporting dog of choice for the common man. Early sporting terriers needed to be big enough to tackle the quarry, but not so big as to prevent them from maneuvering through the quarry's underground lair. Obviously these terriers had to have a very high degree of courage and pluck to face the foe in a tight, dark underground den without the help of human handlers.
During the middle of the nineteenth century, regular sporting events took place along the Aire River in which terriers pursued the large river rats that inhabited the area. A terrier was judged on its ability to locate a "live" hole in the riverbank and then, after the rat was driven from its hole by a ferret brought along for that purpose, the terrier would pursue the rat through water until it could make a kill. As these events became more popular, demand arose for a terrier that could excel in this activity. One such terrier was developed through judicious crossings of the Black-and-Tan Terrier and Bull-and-Terrier dog popular at the time with the Otter Hound. The result was a long-legged fellow that would soon develop into the dog we recognize today as the Airedale Terrier. This character was too big to "go to ground" in the manner of the smaller working terriers; however, it was good at everything else expected of a sporting terrier, and it was particularly adept at water work. This big terrier had other talents in addition to its skill as a ratter. Because of an infusion of hound blood it was blessed with the ability to scent game and the size to be able to tackle larger animals. It became more of a multipurpose terrier that could pursue game by powerful scenting ability, be broken to gun, and taught to retrieve. Its size and temperament made it an able guardian of farm and home. One of the colorful, but less-than legal, uses of the early Airedale Terrier was to assist its master in poaching game on the large estates that were off-limits to commoners. Rabbits, hare, and fowl were plentiful, and the Airedale could be taught to retrieve game killed by its master, or to pursue, kill, and bring it back itself.
