Italian Greyhound Body Structure

The Italian Greyhound’s distinct body structure sets it apart from other dog breeds. With a slender and lightweight frame, their movements exhibit grace and agility. The overall body conformation showcases their athleticism and endurance. Let’s check out some of their body structure characteristics:

Size and Proportions

Italian Greyhounds are considered one of the most miniature sighthound breeds. They have a compact and well-proportioned body, typically measuring between 13 and 15 inches at the shoulder. Despite their small size, they possess a sturdy and athletic build.

Fun Fact: There is an additional minitature version of an Iggy, known as a Teacup Italian Greyhound.

Head and Facial Structure

The Italian Greyhound’s head is an exquisite blend of elegance and refinement. Their skull is long and narrow, with a slightly domed forehead. The eyes are large, expressive, and set well apart. They are known for their soulful gaze, which captures the hearts of many dog lovers. The ears are small, thin, and folded backward, adding to their charm.

Dentition and Bite

Iggies have a well-aligned set of teeth, with a scissors bite being the most desirable. This means that the upper incisors neatly overlap the lower incisors. A correct bite is not only aesthetically pleasing but also crucial for efficient chewing and overall oral health.

Ears and Eyes

Italian Greyhounds are renowned for their expressive eyes, which are large, dark, and full of warmth. Their eyes are set well apart and are known to convey a sense of intelligence and curiosity. The ears of an Iggy are small and thin, often folded backward or carried semi-erect.

Neck and Shoulders

Italian Greyhounds have long and arched necks that blend smoothly into well-laid-back shoulders. This conformation allows for an efficient extension of the front legs during movement, allowing them to cover the ground gracefully and effortlessly.

Chest and Ribs

Italian Greyhounds have a deep chest that reaches down to the elbow. The ribs are well-sprung and extend well back, providing ample lung capacity. This contributes to the breed’s endurance and ability to cover ground effortlessly.

Back and Loins

Italian Greyhounds have a straight and level back, providing a solid foundation for their athletic abilities. Their loins are muscular and slightly arched, contributing to their agility and flexibility.


The hindquarters of an Iggy are well-muscled, with muscular and clearly defined thighs. The breed has a well-angulated stifle joint and low hocks to the ground. These features, combined with their long second thigh, give the Italian Greyhound the ability to generate significant power and drive from the rear.

Limbs and Feet

Italian Greyhounds have long, slim limbs that contribute to their agility. Their front legs are straight and well under the body, while the rear legs are strong and well-muscled. This unique combination of limb structure enables them to execute swift and precise movements, often compared to those of an undersized racehorse.

Their feet are tiny and hare-like, with well-arched toes. The toes are elongated, giving the Italian Greyhound increased grip and traction, essential for quick turns and sudden bursts of speed. Care must be taken to protect their delicate feet from rough surfaces or extreme temperatures.


The tail of an Iggy is long, slender, and tapers to a slight curve. It is set low, reaching at least to the hock joint. The tail is an essential aspect of the breed’s balance and is an expressive feature during movement.

Coat and Colors

The Italian Greyhound’s coat is short, smooth, and glossy. It comes in various colors, including shades of black, blue, gray, fawn, red, and cream. Some Iggies may exhibit markings such as white on the chest, feet, or face. The coat’s fine texture provides minimal protection from extreme temperatures, making it necessary to keep these delicate dogs warm in colder climates.

Italian Greyhound Physiology

Now that we’ve covered an Iggy’s (externally visible) body structure let’s now delve into their physiology:

Skeletal System

The skeletal system of Italian Greyhounds plays a crucial role in their overall form and function. Italian Greyhounds have a delicate and lightweight skeletal structure. Their bones are delicately proportioned, ensuring a lightweight yet sturdy structure. Their legs’ long, delicate bones contribute to their remarkable speed and agility. A flexible spine also allows for efficient extension and contraction, facilitating their graceful movements.

Muscular System

Italian Greyhounds possess well-developed muscles that work harmoniously with their skeletal system. Their lean muscles provide the necessary strength for swift acceleration and deceleration. These powerful muscles are particularly evident in their hindquarters, which are the powerhouse for their incredible speed.

Sensory Organs

Iggies possess keen senses, allowing them to navigate the world around them precisely. Their eyes are large and expressive, conveying a wide range of emotions. Their sense of sight is remarkable, enabling them to spot fast-moving objects and small prey from a considerable distance.

An Iggy’s hearing is also highly developed, capable of detecting subtle sounds that might go unnoticed by other breeds. Italian Greyhounds’ acute senses make them excellent companions and vigilant watchdogs.

Respiratory System

Italian Greyhounds possess a highly efficient respiratory system that supports their active lifestyle. Their lungs have a larger capacity relative to their size, allowing for increased oxygen intake during intense physical activity. This enables them to maintain endurance and perform well during running or competing in agility trials.

Cardiovascular System

The cardiovascular system of Italian Greyhounds is optimized for efficient blood circulation and oxygen delivery. Their hearts are proportionally large, ensuring an adequate blood supply to the muscles and organs. With a high heart rate and stable cardiac output, Italian Greyhounds can sustain their energy levels and excel in activities that demand cardiovascular endurance.

Digestive System

Like all dogs, Italian Greyhounds have a well-developed digestive system that breaks down food and absorbs nutrients. However, their smaller size necessitates careful attention to their dietary needs. Providing them with a balanced diet that meets their nutritional requirements and supports their overall health is essential.

Nervous System

The nervous system of Italian Greyhounds is intricate and finely tuned. Their highly developed sensory perception allows them to observe their surroundings and react swiftly to stimuli keenly. This acute awareness contributes to their exceptional agility and makes them highly responsive to commands during training.

Reproductive System

Italian Greyhounds have a reproductive system similar to other dog breeds. Females experience heat cycles, typically twice a year, during which they may become receptive to mating. Males, on the other hand, reach sexual maturity at around six to eight months. Responsible breeding practices are crucial to ensure the health and well-being of Italian Greyhounds and their offspring.


Italian Greyhounds have a thin coat and minimal body fat, which can make them more sensitive to temperature changes. They are more prone to feeling cold and may require extra protection during colder seasons. Similarly, they can also be more susceptible to heat, so it is crucial to provide them with proper shade and hydration during hot weather.

Immune System

Italian Greyhounds have an immune system that helps protect them against diseases and infections. However, their slim physique and thin skin make them more susceptible to specific health conditions. Maintaining a robust immune system through a nutritious diet, regular exercise, and routine veterinary care is essential for their overall health and longevity.

Health Considerations

While Italian Greyhounds are generally healthy dogs but are predisposed to specific health conditions, these include dental issues, allergies, patellar luxation, and certain genetic disorders. Regular veterinary check-ups and proactive care are essential to ensure early detection and appropriate management of potential health concerns.

Temperament and Personality

Beyond their physical attributes, Italian Greyhounds are known for their endearing personalities. They are affectionate, gentle, and deeply attached to human companions. These intelligent dogs thrive on human interaction and seek comfort and warmth from their loved ones.

Iggies are playful and love engaging in activities that challenge their agility and speed. Despite their small size, they are adventurous and enjoy exploring the world around them. They are adaptable dogs that can easily fit into various lifestyles, making them an ideal choice for individuals and families.
