The Airedale Terrier also called Bingley Terrier and Waterside Terrier is a dog breed of the terrier type that originated in the valley of the River Aire, in the West Riding of Yorkshire, England. Airedale terrier is traditionally called the “King of Terriers” because it is the largest of the terrier breeds. The Airedale was bred from the Old English Black and Tan Terrier (now known as the Welsh Terrier), the Otterhound and probably some other Terrier breeds, and has contributed to other dog breeds, such as the Yorkshire Terrier. Originally bred to serve as a versatile hunting and all-around working farm dog, in Britain this breed has also been used as a war dog, guide dog and police dog. In the United States, this breed has been used to hunt big game, upland birds, and waterfowl, and serve in many other working capacities.

Appearance

The Airedale is the largest of the British terriers. They weigh 19–25 kilograms (42–55 lb) in fit condition and have a height at the withers of 58–61 centimetres (23–24 in) for males, with females slightly smaller.

Like many terriers, the Airedale terrier breed has a ‘broken’ coat, which is hard and wiry. It is meant to be kept not so long as to appear ragged, and lies straight and close, covering body and legs. The outer coat is hard, wiry and stiff, the undercoat softer. The hardest coats are crinkly or just slightly waved. Curly soft coats are highly undesirable.

Traditionally the fluffy tail is long and erect. In most European countries and Australia it is illegal to dock dogs’ tails unless it is for the dog’s benefit (e.g., if the tail is broken). This has resulted in the emergence of a spitz tail in some dogs. Selective breeding should see this change over time and the required slightly curled tail set high on the back again become common.
