The Airedale Terrier (often shortened to "Airedale") is a terrier dog breed originating from Airedale in Yorkshire, England. It traditionally was called the "King of Terriers" because until the advent of the Black Russian Terrier the ADT was largest of the terrier breeds, 40 to 50 pounds. [wikipedia]

The breed has also been called the Waterside Terrier, because it was bred originally to hunt otters in and around the valleys of the River Aire from whence it gets its name.

The Airedale's tail is usually docked (surgically shortened) within five days of birth, but this is not a requirement of breed standard authorities.
