Watch this video for a quick overview of the Greyhound — see the breed in action before diving into the details below.
The Greyhound is the world's fastest dog breed, capable of reaching speeds of 45 mph — faster than a thoroughbred racehorse over short distances. One of the oldest purebred dogs in existence, the Greyhound appears in Egyptian tomb carvings dating to 2900 BC and is the only breed mentioned by name in the Bible. For thousands of years, Greyhounds were so prized that only nobility were permitted to own them, and killing one was once considered a capital offense in parts of medieval England.
Despite their athletic build, Greyhounds are famously calm and gentle in the home — earning the nickname "40-mph couch potato." They are sight hounds with exceptional vision and explosive speed, built for short sprints rather than sustained exercise. A large breed weighing 60–70 lbs with a lean, aerodynamic frame and an extremely short, low-maintenance coat, Greyhounds are affectionate, sensitive, and quiet dogs that make surprisingly excellent apartment companions — provided they get daily opportunities to stretch their legs in a safely enclosed area.

Keep sessions short — 10 to 15 minutes — and always end on a success. Enrolling in a puppy or adult obedience class provides structured learning and valuable socialization.
Greyhounds are generally healthy for their size, though regular screening helps catch issues early. Responsible breeders screen breeding stock for the most common conditions, significantly reducing risk in puppies from health-tested parents.
