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 to swim, which explains the confident, independent streak and the hard, wiry black-and-tan coat. Most weigh 45 to 70 pounds and stand 22 to 24 inches tall.
Airedales are clever, playful and often stubborn, and they bond closely with their families. The coat sheds little but needs clipping or hand-stripping every six to eight weeks, which is worth planning for in Honolulu's year-round warmth. A strong urge to chase is common, so cats and other small pets need careful introductions, and a dog's own history says more than breed reputation.
