The airedale terrier is the largest of the terriers, and is believed to be the result of crossings between the now extinct old english broken-haired terrier, wire-haired earthdogs and otterhounds. The breed first entered the show ring in 1879 and quickly became popular as a show- and companion breed. It has also been kept as a military breed and is a sporty and robust companion.
The ideal airedale terrier should appear confident, brave and loyal. The head is long and flat, with a very small stop and powerful jaws. The ears are small and V-shaped. The neck is of intermediate length, the body short and strong with a deep chest and straight back. The legs are well angulated, with small round paws. The tail is set high and carried happily. The coat is hard, wirey and laying close to the body, trimmed to be longer on the muzzle and legs.
