The Airedale is the largest of the terriers, developed in Yorkshire's Aire Valley to hunt rats, otters and birds. It has a hard, wiry black-and-tan coat, a bearded face and a long-legged, athletic build, usually 45 to 70 pounds. The wiry coat sheds little, but it needs regular clipping or hand-stripping to stay tidy.
Many Airedales are clever, confident and playful, with a stubborn streak and a sense of humor. They tend to bond closely with their families and get bored quickly, so varied training, daily exercise and puzzle toys matter. A strong chase instinct is common, which affects how they do around cats and small pets. Each dog is different, so a dog's own behavior counts for more than breed reputation.
