Called the King of Terriers, the Airedale is the largest of the terrier breeds. Mill and factory workers in Yorkshire's Aire Valley developed it in the mid-1800s from old black-and-tan terriers and the Otterhound, and it went on to hunt rats and otters and to carry messages in World War I. Adults usually weigh 45 to 70 pounds and wear a hard, wiry black-and-tan coat with a beard and folded ears.
Many Airedales are clever, confident and playful, with a stubborn streak and a low boredom threshold. They tend to bond closely with their people, and a strong chase drive is common. In Reno, that means a secure yard or a leash around small animals and wildlife at the edge of town. The coat needs regular clipping or hand-stripping, though dogs vary in how much upkeep they need.
