AKC Meet the Breeds: Airedale Terrier
The undisputed "King of Terriers," the Airedale Terrier is the largest and hardiest of the terriers, and an all around useful dog. The breed's coat is hard, dense and wiry, with a softer undercoat, and comes in both tan and black and tan and grizzle. This breed was one of the first used for police duty in Germany and Great Britain and has also been popular with Presidents, including Woodrow Wilson, Warren Harding and Calvin Coolidge.
A Look Back
The Airedale is thought to have originated in the valley of the Aire in England, descended from the now-extinct black-and-tan type terrier.
The first Airedales looked completely different from how they appear today, and were known as Working, Waterside and Bingley Terriers. Eventually, the Airedale became known as a dog that could do it all, and was used for wartime guard, messenger duty, rodent control and hunting birds and game.
Right breed for you?
The Airedale has a sweet disposition, but when challenged, is not afraid to stand up for himself. Obedience training is important for these quick learners, but make sure to keep it interesting - they can get bored easily! They also thrive with daily exercise, both mental and physical. Although relatively easy to maintain, the Airedale coat needs regular brushing and stripping.
