Called the King of Terriers, the Airedale is the largest of its group. Mill and factory workers in Yorkshire's Aire Valley developed it in the mid-1800s, crossing old black-and-tan terriers with the Otterhound to get a dog that could hunt rats and otters and swim well. It later carried messages in World War I. The hard, wiry coat is black and tan, with a bearded face and folded ears.
Many Airedales are confident, playful and a little stubborn. They bond closely with their families, bore easily, and do best with varied training and daily exercise. A strong urge to chase squirrels and other small animals is common, so a secure leash matters on Charlotte's greenways. The coat sheds little but needs regular clipping or stripping.
