Lagotto Romagnolo Breed Profile & Growth Guide

Breed Overview

The Lagotto Romagnolo is an ancient Italian breed originally developed in the Romagna region for water retrieving and later adapted for truffle hunting. With its dense, curly, and waterproof coat, the Lagotto is well-suited for working in wet and rugged environments. This breed is renowned for its intelligence, keen nose, and affectionate, loyal temperament.

Lagottos are friendly, eager to please, and generally get along well with children and other pets. They’re quick learners and thrive in active households that provide both physical and mental stimulation.

Size Category: Medium
The Lagotto Romagnolo is classified as a medium-sized breed, with adults typically weighing 24–35 lbs. Growth tracking is especially important to prevent under- or overfeeding during key developmental stages. Because they’re an athletic working breed, proper growth supports joint health and long-term mobility.

How Much Bigger Will My Lagotto Romagnolo Puppy Get?

Lagotto puppies grow rapidly in the first 6 months, with most reaching near their adult size by their first birthday.

• 50% of adult weight by 4 months
• 75% by 6–7 months
• Full adult weight by 12 months

Rule of thumb:
Double your puppy’s weight at 16 weeks to estimate their adult size.

Exceptions:
While most Lagottos reach their full height by 9–12 months, some may continue to fill out in muscle and coat density until about 18 months.

Lagotto Romagnolo Growth Tips

Nutrition

• Feeding Schedule: Feed 3 times daily until 6 months old, then transition to 2 meals per day.
• Choose a high-quality, medium-breed puppy food with balanced protein and fat levels to support healthy growth.
• Avoid overfeeding, as Lagottos can be prone to weight gain if not properly exercised.

Exercise

• Provide daily physical activity such as walks, fetch, and safe off-leash play.
• Avoid strenuous jumping or long runs before 12 months to protect developing joints.
• Stimulate their mind with scent work, training games, or beginner agility—this breed thrives on mental challenges.

Health Watch

• Hip dysplasia: Although not extremely common, it’s a concern in many medium-sized working breeds. Maintain a healthy weight and avoid over-exercising during growth.
• Ear infections: Due to their floppy ears and love of water, check ears regularly and keep them clean and dry.
• Lagotto Storage Disease (a rare neurological condition) is hereditary—choose a reputable breeder who health tests their dogs.
