19 Airedale Terriers
The Airedale Terrier (often shortened to "Airedale") is a breed of the terrier type that originated in Airedale, a geographic area in Yorkshire, England. It is traditionally called the "King of Terriers" because it is the largest of the terrier breeds. Bred from a Welsh Terrier and an Otterhound, 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 which runs through Airedale. In the United Kingdom this breed has also been used as a police dog. The Airedale is the largest of the British Terriers. They weigh 25–30 kilograms (55–66 lb) and have a height at the withers of 58–61 centimetres (23–24 in) for dogs, with females slightly smaller.
