The Airedale is the largest of the terriers, developed in the mid-1800s in Yorkshire's Aire Valley from old black-and-tan terriers and the Otterhound. It was built to hunt rats and otters and swim after them, which explains the long legs, the hard black-and-tan coat and the beard. Most Airedales weigh 45 to 70 pounds.
Many Airedales are clever, confident and funny, with a stubborn streak. They bond closely with their families and bore easily, so varied training and daily activity help. In Fishers, that means putting the trails and a fenced yard to work, and watching closely around squirrels and rabbits, since a strong urge to chase small animals is common. Each dog is different, so spend time with the dog before deciding.
