How big do Italian Greyhounds get?

How big is a fully grown Italian Greyhound?

A fully grown Italian Greyhound is a compact, manageable size, typically weighing between 3–5kg. This puts them in the small dog bracket.

Male Italian Greyhounds tend to be larger than females, generally weighing toward the upper end of that range. Females are typically lighter and slightly shorter. Individual variation within the breed is normal — genetics, diet, and health all play a role.

When do Italian Greyhounds stop growing?

Italian Greyhounds reach their full adult height fairly quickly, but continue to fill out in muscle and bulk after that. Small breeds mature quickly — Italian Greyhounds often reach their full adult size by 8–12 months, sometimes as early as 6 months. What they lack in size they more than make up for in longevity: smaller dogs consistently live longer than larger breeds.

Is a Italian Greyhound the right size for me?

Size matters more than people realise when choosing a dog. Here's what 3–5kg means in practice:

• Food costs are lower. Small dogs eat less. Annual food bills are significantly cheaper than large breeds.
• Vet costs can still be high. Size doesn't always mean lower vet bills, especially for breeds prone to dental or kneecap issues.
• Better for small spaces — a Italian Greyhound can thrive comfortably in a flat or smaller home.
• Travel is easier. They fit in-cabin on many airlines and in the footwell of a car.

How do I keep my Italian Greyhound at a healthy weight?

The target range for an adult Italian Greyhound is 3–5kg. A simple check: you should be able to feel their ribs without pressing hard, but you shouldn't be able to see them. Viewed from above, there should be a visible waist.

Obesity is the most preventable health problem across all dog breeds — and Italian Greyhounds are not immune to it. Measure food portions rather than estimating, limit treats to 10% of daily calories, and factor in daily exercise as part of their routine.

If you're unsure whether your Italian Greyhound is a healthy weight, ask your vet at their next annual check-up. Most practices offer free nurse weight clinics.
