Indoors the Whippet is usually quiet, gentle and fond of comfort, and it often seeks out soft bedding and close contact with its people. Outdoors it is playful and quick to chase anything small that runs. It tends to be sensitive and does not respond well to harsh handling.
The breed is built for short bursts of speed. It has a long, fine head, small folded ears, a long neck, a deep chest and a firm back with a definite arch over the loin above strong, muscular hindquarters. The coat is short, fine and close, and breed standards accept almost any colour or pattern, so fawn, brindle, black, blue and white-patched dogs are all seen.
The Whippet was recognised by the Kennel Club in the late nineteenth century, by which time it had become a fixture of working-class sport. Its early breeders are generally thought to have crossed small Greyhounds with terriers, and perhaps the Italian Greyhound, though no exact record survives. It was often called the poor man's racehorse, and in rag racing each dog sprinted down a straight track towards its owner, who waved a cloth at the finish.
