Airedale Terrier

The Airedale Terrier (often shortened to "Airedale") is a breed of the terrier type, that first came from Airedale, a geographic area in Yorkshire, England. 
It traditionally was called the "King of Terriers" because before the creation of the Black Russian Terrier, the Airedale was largest of the terrier breeds. The breed has also been called the Waterside Terrier, because it was bred to hunt otters in and around the valleys of the River Aire in Airedale. In England this breed has also been used as a police dog.
