At first glance, greyhounds and Italian greyhounds seem like they are of different sizes and the same elegant breed. Their sleek, aerodynamic builds, long legs, and deep chests scream speed and agility. But despite their visual similarities, these two breeds have distinct differences in size, temperament, and care requirements.
If you’ve ever wondered whether a Greyhound or an Italian Greyhound would be the right fit for your home, you’re in the right place!
This detailed comparison will explore how Greyhounds and Italian Greyhounds differ in size, coat type, temperament, health, and lifespan. Whether you’re looking for a graceful, couch-loving giant or a petite, playful lap dog, this guide will help you make the right choice.
Greyhound vs. Italian Greyhound
Greyhounds and Italian Greyhounds belong to the sighthound family, meaning they rely on their exceptional vision and speed to chase prey. However, their histories and original purposes set them apart. Greyhounds were bred for hunting large game and later became racing champions, prized for their unmatched acceleration and endurance.
On the other hand, Italian Greyhounds were bred as companions for nobility, especially during the Renaissance period, when they became beloved lapdogs of European aristocracy.
Size is the most noticeable difference between the two breeds. Greyhounds are much larger, standing between 26-30 inches tall and weighing 50-85 pounds. Italian Greyhounds, in contrast, are delicate and petite, measuring only 13-15 inches in height and weighing a mere 7-14 pounds.
Their smaller size makes them more suited for apartment living, while Greyhounds need more space to stretch their long legs.

Despite their differences, both breeds share a love for relaxation and make fantastic house pets. Greyhounds are often referred to as “40-mph couch potatoes” due to their ability to go from racing speeds to deep naps in minutes.
Italian Greyhounds are required to be close to their owners. While also loving snuggle time, they tend to be more playful and energetic throughout the day, requiring extra mental stimulation to stay happy.
Greyhound vs. Italian Greyhound: Physical Appearance
While both breeds have the same slender, deep-chested silhouette designed for speed, their size and proportions create striking differences.
Greyhounds have longer legs, larger heads, and a more muscular build, making them one of the fastest land animals, capable of reaching speeds up to 45 mph. Their lean yet strong physique is designed for bursts of energy, making them efficient sprinters.

Italian Greyhounds, though similarly built, have a finer bone structure and a more delicate frame. Their long, slender legs and tiny paws make them look almost fragile, and they are more prone to injuries compared to their larger relatives. While they can still reach impressive speeds, they lack the endurance and power of a Greyhound, making them better suited for short sprints rather than sustained runs.

One of the most endearing physical differences is their facial expressions. The American Kennel Club says Greyhounds have a more stoic and regal look, while Italian Greyhounds often have an expressive, wide-eyed appearance that makes them look eternally curious and affectionate. This combination of physical traits plays a big role in their personality and how they interact with their humans.
Greyhound vs. Italian Greyhound: Coat Type
Both breeds have short, smooth coats that require minimal grooming, but there are subtle differences in texture and care. Greyhounds have a slightly thicker, denser coat that provides some protection from the elements.
However, they still have very little body fat, meaning they get cold easily and benefit from dog sweaters or coats in chilly weather.
Italian Greyhounds have even thinner coats, making them particularly sensitive to cold. Their skin is delicate, and they can develop pressure sores if they lie on hard surfaces for too long. Due to their fine coat, they are more prone to skin irritations and sunburn, so they require extra care in extreme temperatures.

Neither breed sheds excessively, making them great options for people who prefer a low-maintenance dog. A quick weekly brush is enough to keep their coats in good condition. Bathing is rarely necessary unless they get particularly dirty, and their short fur makes them easy to keep clean with just a wipe-down.

Greyhound vs. Italian Greyhound: Temperament
Both Greyhounds and Italian Greyhounds are affectionate, gentle, and deeply bonded with their owners. However, their personalities differ when it comes to independence and energy levels.
WebMD says Greyhounds are calm, quiet, and composed. They are known for being adaptable and easygoing, making them fantastic pets for first-time dog owners. While they love their humans, they are not overly clingy and can enjoy independent moments.
They tend to be reserved around strangers but are not aggressive, making them excellent companion animals.

Italian Greyhounds, on the other hand, are much more sensitive dogs and attached. They crave constant companionship and often suffer from separation anxiety if left alone for too long. They are playful, energetic, and sometimes a little mischievous, making them better suited for owners who can dedicate a lot of time to training and engagement.
Greyhounds are surprisingly easy to potty train, especially for a breed that has often lived in a kennel environment before adoption. They are naturally clean dogs, and once they learn the routine, they rarely have accidents inside.
Greyhounds respond well to positive reinforcement training, and since they are eager to please their owners, they pick up housebreaking quickly.
Their affectionate nature makes them wonderful lap dogs, but they can also be more demanding than their larger cousins.
Greyhound vs. Italian Greyhound: Health Considerations
Greyhounds and Italian Greyhounds share some common health concerns, but their size impacts their vulnerabilities. Omlet says Greyhounds are prone to bloat, hip dysplasia, and osteosarcoma (bone cancer), particularly as they age. Due to their low body fat, they are also sensitive to anesthesia, requiring specialized veterinary care.
As per Orvis, Italian Greyhounds are more fragile and prone to leg fractures due to their fine bone structure. They also have dental issues, as their small mouths often lead to overcrowded teeth and gum disease. Like Greyhounds, they are also sensitive to cold weather and require warm bedding and clothing in cooler temperatures.

Despite these concerns, these furry friends can lead long, healthy lives with proper care when compared to other breeds. A well-balanced diet, regular vet checkups, and mindful exercise can significantly improve their quality of life.
Greyhound vs. Italian Greyhound: Life Expectancy
Italian Greyhounds have a longer lifespan, typically living between 12-15 years, while Greyhounds average around 10-14 years. The miniature greyhound’s longer life expectancy is common among toy and small dog breeds, while Greyhounds, being a larger breed, tend to have a slightly shorter lifespan.
Both breeds can enjoy long and happy lives with proper nutrition, exercise, and veterinary care. Adopting retired racing Greyhounds is a great way to provide a loving home for a dog in need, while Italian Greyhounds are ideal for owners who want a long-term, devoted companion.

Conclusion
Choosing between a Greyhound and an Italian Greyhound depends on your lifestyle and what you’re looking for in a pet. A Greyhound might be the perfect fit if you want a larger, more independent, and relaxed dog that enjoys lounging as much as running. An Italian Greyhound could be your ideal match if you prefer a smaller, affectionate, and playful companion who thrives on attention and interaction.
Both breeds are loving, elegant, and wonderful pets, offering years of companionship to the right owner when compared to other dogs. Whether you choose the sleek speedster or the pocket-sized charmer, you’re guaranteed a loyal and affectionate best friend! small animal
