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 hunted rats and otters, swam well and later worked as a messenger dog in World War I. The look is a wiry black-and-tan coat, a bearded face and folded ears on a long-legged, athletic frame.
Many Airedales are clever, confident and playful, with a stubborn streak. They bond closely with their families but bore easily, so varied training and daily exercise matter. In Fort Lauderdale, the low-shedding wire coat needs regular clipping or hand-stripping, and a strong chase drive calls for a leash around the canals. Dogs vary, so spend time with the one you're considering.
