Called the King of Terriers because it's the largest of them, the Airedale was developed in the mid-1800s by mill and factory workers in Yorkshire's Aire Valley. Crossing old black-and-tan terriers with the Otterhound produced a tough dog that hunted rats and otters, swam well and later carried messages in World War I. Most weigh 45 to 70 pounds and have a hard, wiry black-and-tan coat and a bearded face.
Many Airedales are clever, confident and playful, with a sense of humor and a stubborn streak. They bond closely with their families but bore easily, 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, which is worth remembering on busy Columbus greenways.
