How can you tell the difference between an Airedale and Wirehaired Fox Terrier?

The Airedale Terrier is larger, typically weighing between 40-65 pounds and standing about 21-23 inches tall, while the Wirehaired Fox Terrier is smaller, usually weighing 15-20 pounds and standing around 15-18 inches tall. Airedales have a more elongated head and a longer body, whereas Wirehaired Fox Terriers have a more compact build and a distinctively square shape. Additionally, the Airedale has a smoother, flatter coat compared to the wiry, rough coat of the Wirehaired Fox Terrier. The facial expressions and ear shapes also differ, with Airedales having a more pronounced beard and longer, folded ears, while Wirehaired Fox Terriers have smaller, more erect ears.
