The Whippet (also English Whippet or Snap Dog) is a dog breed of medium size. The Whippet was held in high regard in the northern parts of England and Wales, but was generally disregarded in the rest of the country. At the time, there were two varieties of Whippet. The first type had a smooth coat, was more popular in Lancashire, Yorkshire, and the Midlands, and became the modern Whippet. Many racing dogs were part Terrier, part Greyhound, or part Lurcher. In 1967, the British Whippet Racing Association was established to bring around reform and consistency in race rules and procedures for races involving non-purebred Whippets. A year later, viewing the non-purebred dogs as a threat, the Whippet Club Racing Association was established exclusively for purebred animals. Whippets are quiet and not prone to barking, but require regular exercise. They are generally gentle dogs and may be content to spend much of the day resting.
