The Greyhound is an ancient sighthound type refined in England to chase game by sight. A deep chest, long legs and a flexible back let it top 40 miles per hour. In the United States, most pet Greyhounds are retired racers, usually between two and five years old, so adopters often meet an adult with a settled personality. Kennel life means house manners, stairs and glass doors are all new.
Indoors, many Greyhounds are calm, sleep much of the day and rarely bark. Thin skin and a short coat mean they feel cold quickly and need soft bedding. A strong chase instinct means cats and small dogs call for careful introductions, and squirrels and pigeons in Brooklyn's parks are reason enough to keep a Greyhound on a leash. Dogs vary, so each Greyhound's own habits matter more than the breed's reputation.
