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. The other had a rough coat from crossbreeding with Bedlington Terriers. This type was more popular in Durham and Northumberland and was frequently referred to as a 'rabbit dog'. Described as a 'narrow dog' he lent his name to the book's titles - Narrow Dog to Carcassonne, Narrow Dog to Indian River and Narrow Dog to Wigan Pier.
