Called the King of Terriers, the Airedale is the largest of the terrier group. Mill and factory workers in Yorkshire's Aire Valley developed it in the mid-1800s from old black-and-tan terriers and the Otterhound, aiming for a dog that could hunt rats and otters and swim well. Most adults weigh 45 to 70 pounds and have a wiry black-and-tan coat, a bearded face and folded ears.
Many Airedales are clever, confident and playful, with a stubborn streak and a sense of humor. They bond closely with their families and bore quickly, so varied training and daily activity matter. The coat sheds little but needs regular clipping or hand-stripping, and in rainy Nashville that wiry coat and beard will carry plenty of mud indoors. Chasing small animals is common.
