Things to keep an eye on

Gastric Dilatation-Volvulus (Bloat)

high

Deep-chested breeds like the Neapolitan Mastiff are at a higher risk for this life-threatening condition where the stomach fills with gas and twists. Immediate veterinary attention is required if the abdomen appears distended or the dog is restless.

Feed smaller, frequent meals rather than one large meal and avoid vigorous exercise immediately after eating.

Hip Dysplasia

high

This is a common orthopedic condition in large breeds where the hip joint does not fit together perfectly, potentially leading to mobility issues. It is often managed through weight control and supportive care.

Maintain a lean body weight throughout the dog's life to reduce stress on the joints.

Dermatitis in skin folds

moderate

The heavy wrinkles of the Neapolitan Mastiff can trap moisture and debris, creating an environment where bacteria or yeast can thrive. Keeping these areas clean is essential for skin health.

Gently wipe and dry the skin folds daily to prevent moisture buildup.

Ectropion and Entropion

moderate

Due to their facial structure and loose skin, these dogs may experience eyelid abnormalities where the eyelid rolls outward or inward, causing irritation to the eyes. Regular observation of the eyes for redness or discharge is recommended.

Keep the facial folds clean and dry to prevent secondary infections and monitor eyes daily.

General patterns, not a diagnosis — always check with your vet.
