The Greyhound is the fastest dog on earth and the most surprising pet in this list — because the dog people imagine (a hyperactive racing machine) is almost the opposite of the dog they get. A 27-39 kg sighthound built for explosive 70 km/h sprints, the Greyhound is also, off the track, one of the calmest, quietest, lowest-energy companions in dogdom. The breed's nickname among adopters is '40 mph couch potato', and it is accurate: a healthy adult Greyhound is content with two or three short walks and a couple of sprints a week, and spends the rest of the day asleep. The mismatch to manage is not energy — it is the dog's unique physiology and its prey drive. Three honest cautions define ownership. First, anaesthesia: Greyhounds have very low body fat and an unusual liver-enzyme profile, so standard anaesthetic doses and protocols can be dangerous or fatal. This is not a footnote — it is a sentence you must say to every vet before any sedation or surgery, and it is the reason Greyhound-experienced vets matter. Second, the prey drive: a sighthound will chase a fleeing cat, squirrel or small dog instinctively and can be gone at 60 km/h before you react, so off-lead freedom in unfenced areas is generally unsafe. Third, the body itself: almost no fat means poor cold tolerance (this dog needs a coat outdoors in winter and a padded bed indoors) and bony pressure sores on hard floors. Physically the Greyhound stands 69-79 cm at the shoulder, deep-chested, fine-skinned, with a short, near-maintenance-free coat. Lifespan is shorter than many comparable dogs at roughly 8-12 years, and bloat and bone cancer are real shadows over the back half of that. Temperament is gentle, sensitive, quiet, affectionate and notably non-aggressive — superb with calm households and often with children, and famously good apartment dogs. The Greyhound is right for an owner who wants a gentle, low-exercise, sensitive companion, will manage prey drive and cold, and will brief every vet about anaesthesia. It is wrong for homes with free-roaming small pets the dog can't be separated from, owners who want an off-lead trail dog, or anyone unwilling to use a Greyhound-aware vet.

The Greyhound is one of the oldest dog breeds, a sighthound type depicted in art for thousands of years and long associated with nobility — for centuries in England the breed was protected by law and ownership restricted to the aristocracy. It was bred purely for coursing: spotting and running down fast game (especially hares) by sight and raw speed across open ground. The sport of coursing, and later track racing in the 20th century, shaped the …
Greyhound dog breed portrait
Greyhounds can reach speeds of 45 mph (72 km/h), making them the fastest dog breed in the world
Despite their speed, Greyhounds are known as "45-mph couch potatoes" because they sleep 16-18 hours a day
They are the only dog breed mentioned by name in the Bible (Proverbs 30:29-31)
Greyhounds have been found depicted in art dating back to ancient Egypt over 4,000 years ago
They have a unique double-suspension gallop — all four feet leave the ground twice during each stride

A Greyhound costs $500–$2,500 to purchase from a reputable breeder, plus roughly $120/month in ongoing expenses — food, veterinary care, grooming, and insurance. Over a 8–12-year lifespan, total lifetime ownership cost runs $11,520–$17,280. Adopting from a rescue ($50–$500) reduces the upfront cost significantly. The first year is always the most expensive due to initial setup costs ($300–$800) on top of the purchase price.
Prices vary based on lineage, breeder reputation, location, and whether the Greyhound is pet-quality or show-quality. Adopting from a rescue or shelter typically costs $50–$500 and gives a Greyhound a second chance at a loving home.

Greyhound care is light on exercise and heavy on physiology awareness. Exercise: two or three 20-30 minute walks a day plus the chance to sprint safely a few times a week is plenty — this is a sprinter, not an endurance dog, and it does not need or want hours of activity. Walk on lead or in fully fenced areas only; the chase instinct overrides recall. Feeding and bloat: feed two or three smaller measured meals rather than one large one, and avoid heavy exercise within an hour either side of eating. Deep-chested breeds are at elevated risk of GDV (bloat), a rapid, fatal stomach torsion — a hard, distended abdomen, unproductive retching and restlessness is a same-minute emergency. Body and comfort: with almost no body fat, Greyhounds need a thick padded bed (pressure sores form on elbows and hips on hard floors) and a coat in cold or wet weather. Keep the dog at a lean racing-fit weight — you should see the last two ribs and the hip points; over-feeding a Greyhound to a 'normal-looking' dog is actually overweight. Dental: thin enamel and crowding make periodontal disease near-universal — brush teeth several times a week and budget for professional cleanings, which require the anaesthesia caution below. Anaesthesia (non-negotiable): tell every veterinarian, before any sedation, dental or surgery, that this is a Greyhound — low body fat and altered drug metabolism mean standard protocols can be lethal and dose/agent must be adjusted. Decision rule: bloat signs (distended hard belly, non-productive retching) or sudden lameness/limb swelling in an older Greyhound (possible osteosarcoma) are same-day emergencies — and never allow anaesthesia from a vet who is not briefed on the breed.
