Called the King of Terriers, the Airedale is the largest of the 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, aiming for a tough dog that could hunt rats and otters and swim well. It has a hard, wiry black-and-tan coat, a bearded face, folded ears and a long-legged frame, and many adults weigh 45 to 70 pounds.
Many Airedales are clever, confident and playful, with a stubborn streak and a strong urge to chase small animals. In Indy that means leashed outings on the Monon Trail or the Fall Creek Greenway, and a secure fence if you have a yard. The coat sheds little but needs clipping or hand-stripping every six to eight weeks. Dogs vary, so meet each one as the dog it is.
