Lifespan 10–14 yrs Weight 55–80 lb Gentle & quiet
Greyhound dog: Famously gentle, quiet, and calm indoors, this breed is affectionate with its family in a dignified way — clean, undemanding, and professional about one thing above all: lounging.
Sighthounds resembling this breed appear in ancient Egyptian art thousands of years old. They were prized coursing dogs of nobility, bred for the explosive sprint that catches hares. The Greyhound dog has an ancient history.
Because so many retired racers are placed through adoption groups each year, many owners meet this breed as an adult: typically well-socialized, often crate-trained, and ready to settle into home life from the first week. The Greyhound dog often arrives as an adult.
That sprint drive is real outdoors, but it switches off at the front door. At home, expect a calm, tidy companion that folds itself into impossibly compact sleeping positions and saves its speed for the next short burst in a fenced field. The Greyhound dog rests well after a sprint.
At a Glance
Size and Weight
Tall, sleek, and light for the height — the build is all aerodynamics: deep chest, tucked waist, long legs. The Greyhound dog is tall and light.
Males stand 28 to 30 inches and weigh 65 to 80 pounds; females are 27 to 28 inches and 55 to 65 pounds.
They are larger than people expect but lighter than they look.
Coat and Colors
Short, fine, and easy: a very short, smooth coat in black, white, fawn, brindle, blue, or combinations. The Greyhound dog has a short, smooth coat.
Shedding is light, and grooming is minimal — occasional brushing and baths are all the coat asks for.
The thin coat and low body fat mean they feel the cold; sweaters are essential in cool weather.
History and Origins
Sighthounds resembling this breed appear in ancient Egyptian art thousands of years old.

Today’s racing dogs descend from these coursing dogs.
Thousands of retired racers need homes every year, making adoption the breed’s defining story.
One of the oldest breeds in existence, this sighthound has been shaped by millennia of selection for speed. Its modern chapter is written by the families who adopt retired racers and discover how gentle a sprinter can be. The Greyhound dog is among the oldest breeds.
Physical Characteristics

They can be sensitive and a little aloof with strangers. They are rarely aggressive and almost never nuisance barkers.

The sensitivity and chase instinct set the limits. The breed can be sensitive and a little aloof with strangers, rarely aggressive and almost never a nuisance barker, while the chase instinct varies by individual and must be tested, especially with cats. Many are cat-trainable, but never assume, and off-leash in unfenced areas is never an option.

Care Essentials
Surprisingly easy: short daily walks, a warm coat in winter, measured meals, and a soft place to sleep cover most of the daily reality. The Greyhound dog needs only modest daily care.
A typical day is surprisingly easy. Short daily walks, a warm coat in winter, measured meals, and a soft place to sleep cover most of the daily reality, with safe sprint opportunities a few times a week in a fenced area completing it. The calm, tidy companion that results folds itself into impossibly compact sleeping positions.
Measured, high-quality meals twice a day. Keep them lean; the tucked waist should be visible.
Occasional brushing and baths as needed, with regular nail trims and teeth brushing.
20 to 30 minutes of walking daily, plus occasional sprint opportunities in a fenced area.
A calm indoor home, sweaters in cold weather, and a leash or a fence outdoors — always.
Nutrition and Diet
Lean athletes, straightforward feeding: a measured, high-quality diet in two meals a day. The Greyhound dog thrives on measured meals.
Keep them lean; the tucked waist should be visible. Retired racers may need diet transitions; ask your vet.
Feeding suits a lean athlete. A measured, high-quality diet in two meals keeps the tucked waist visible, and retired racers may need diet transitions, so asking the vet keeps the change smooth. Keeping the dog lean matters more than usual, since the aerodynamic build is meant to stay light.
Grooming
Minimal effort: occasional brushing, baths as needed, regular nail trims, and teeth brushing.
Dental care matters; the breed can be prone to dental issues.
Grooming is minimal effort, as the guide says. Occasional brushing and baths as needed cover the very short, smooth coat and its light shedding, while regular nail trims and teeth brushing complete the routine. Dental care matters most of all, since the breed can be prone to dental issues.
Exercise and Enrichment
Low energy with sprint needs: aim for 20 to 30 minutes of walking daily plus safe sprint opportunities a few times a week in a fenced area. That is genuinely enough for most of these dogs.
Mental enrichment through gentle training and sniffy walks suits the calm temperament.
They cannot be trusted off-leash in unfenced areas; the chase instinct overrides everything at 40 mph.
Exercise is low-energy with sprint needs. Twenty to thirty minutes of walking daily plus safe sprint opportunities a few times a week in a fenced area are genuinely enough for most of these dogs, with mental enrichment through gentle training and sniffy walks suiting the calm temperament. The chase instinct overrides everything at 40 mph, so fenced sprinting is the rule.
Health
Most live 10 to 14 years and are generally healthy. Here are the health issues to know:
The critical breed-specific concern; vets must know the protocols for sighthounds.
Bloat can occur, as it can in other deep chested breeds.
Dental disease is common, so regular teeth brushing matters.
Osteosarcoma (bone cancer) appears in the breed.
Corns on the feet bother some individuals.
Schedule annual wellness exams, or twice-yearly exams for seniors, and make sure your vet understands sighthound anesthesia protocols. Consult your veterinarian promptly if you notice lameness, or changes in appetite, weight, or energy. For general background, see the Britannica guide.
Health care follows the familiar rhythm with sighthound awareness in focus. Annual exams, twice-yearly exams for seniors, and a vet who understands sighthound anesthesia protocols cover the ground the guide names, and adoption groups placing retired racers usually share the health history honestly. Day to day, lameness and changes in appetite, weight, or energy deserve a prompt vet call.
Indoor and Outdoor Living
Indoor lounger, outdoor sprinter: this breed lives indoors and is among the best apartment dogs there are — quiet, clean, and low-energy between walks.
They need sweaters in cold weather and should never be off-leash outside fenced areas.
A fenced yard is wonderful for zoomies but not required with regular walks. They live indoors by need as much as by preference: the thin coat offers little protection from the cold.

Finding a Dog: Adoption First
The breed’s story is adoption. Adoption groups place thousands of retired racers yearly, and for most people, adoption is the best path to one of these dogs.
These are typically well-socialized, crate-trained, gentle adults, often at a fraction of breeder cost.
- Ask the adoption group about the dog’s temperament and history
- If you have cats, ask whether the dog has been cat-tested
- Ask what the dog already knows — many retired racers are crate-trained
- Make sure your vet understands sighthound anesthesia protocols
