The Greyhound is an ancient sighthound type refined in England to chase game by sight. Its deep chest, long legs and flexible back make it one of the fastest dogs alive, yet most pet Greyhounds in the United States are retired racers, usually between two and five years old. They typically weigh 55 to 85 pounds and live 10 to 14 years.
At home, many Greyhounds are calm, gentle and quiet, sprinting for a few minutes and then sleeping most of the day. The short coat sheds lightly, but thin skin and little body fat mean they chill fast and need soft bedding. Chase instinct varies from dog to dog, so cats and small pets need careful introductions. A newly retired racer may also need time to learn stairs, glass doors and house life.
