How big do Spinone Italianos get?

How big is a fully grown Spinone Italiano?

A fully grown Spinone Italiano is a substantial dog, typically weighing between 29–39kg. This puts them in the large dog bracket.

Male Spinone Italianos 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 Spinone Italianos stop growing?

Spinone Italianos reach their full adult height fairly quickly, but continue to fill out in muscle and bulk after that. Large breeds like the Spinone Italiano typically reach full adult size at around 12–18 months. Their skeleton reaches full height first, followed by muscle development over the next several months. Until they're fully grown, avoid high-impact exercise (jumping, running on hard surfaces) to protect developing joints.

Is a Spinone Italiano the right size for me?

Size matters more than people realise when choosing a dog. Here's what 29–39kg means in practice:

• Food costs increase with size — a Spinone Italiano at 39kg needs significantly more food than a small breed.
• Space requirements — a large breed needs room to move. A small flat works if exercise needs are met, but they do better with outdoor space.
• Pet insurance is higher. Larger breeds cost more to insure because treatments and surgeries scale with body weight.
• Lifespan is affected — large breeds live 10–12 years on average.

How do I keep my Spinone Italiano at a healthy weight?

The target range for an adult Spinone Italiano is 29–39kg. 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 Spinone Italianos 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 Spinone Italiano is a healthy weight, ask your vet at their next annual check-up. Most practices offer free nurse weight clinics.
