Called the King of Terriers, the Airedale is the largest of the terrier group. Mill and factory workers in Yorkshire's Aire Valley developed it in the mid-1800s by crossing old black-and-tan terriers with the Otterhound. The result hunted rats, otters and birds, and swam well. Airedales have a hard, wiry black-and-tan coat, a long head with a beard and folded ears, and a long-legged, athletic frame.
Many Airedales are clever, confident and playful, with a stubborn streak, and they tend to bond closely with their families. They bore quickly, so varied training and daily exercise matter. The coat sheds little but needs regular stripping or clipping, and a strong urge to chase small animals is common. In Yakima, that means a secure yard and a firm grip on the leash.
