The Airedale is the largest of the terriers, developed in the mid-1800s in Yorkshire's Aire Valley from old black-and-tan terriers and the Otterhound. Mill workers wanted a dog that could hunt rats and otters and swim after them, and the result was a tough, athletic dog with a wiry black-and-tan coat, a long bearded face and folded ears.
Many Airedales are confident, funny and stubborn, and they bond closely with their families. They bore easily, so varied training and daily jobs matter, and a strong chase instinct toward small animals is common. In a city full of squirrels and rabbits, that means a secure leash and a fenced yard. The coat sheds little but needs regular clipping or hand-stripping. Every Airedale differs, so look at each dog's own energy and manners.
