How big do Maremma Sheepdogs get?

How big is a fully grown Maremma Sheepdog?

A fully grown Maremma Sheepdog is a substantial dog, typically weighing between 30–45kg. This puts them in the large dog bracket.

Male Maremma Sheepdogs 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 Maremma Sheepdogs stop growing?

Maremma Sheepdogs reach their full adult height fairly quickly, but continue to fill out in muscle and bulk after that. Large breeds like the Maremma Sheepdog 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 Maremma Sheepdog the right size for me?

Size matters more than people realise when choosing a dog. Here's what 30–45kg means in practice:

• Food costs increase with size — a Maremma Sheepdog at 45kg 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 11–13 years on average.

How do I keep my Maremma Sheepdog at a healthy weight?

The target range for an adult Maremma Sheepdog is 30–45kg. 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 Maremma Sheepdogs 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 Maremma Sheepdog is a healthy weight, ask your vet at their next annual check-up. Most practices offer free nurse weight clinics.
