The Airedale is the largest of the terriers, nicknamed the King of Terriers. Yorkshire mill workers in the Aire Valley developed it in the mid-1800s to hunt rats and otters and to swim after game. It stands 22 to 24 inches tall and usually weighs 45 to 70 pounds, with a hard, wiry black-and-tan coat, a beard and folded ears.
Many Airedales are confident, playful and funny, with a stubborn streak and a strong urge to chase small animals. They bond closely with their people but get bored fast, so varied training and daily jobs matter. The coat sheds little, but it needs regular clipping or hand-stripping, and Atlanta's coyotes make a secure fence and leashed walks worth having.
