The Neapolitan Mastiff is classified by The Royal Kennel Club within the giant ageing band, typically weighing 50–70 kg as an adult. Descended from the war dogs of ancient Rome, the Neapolitan Mastiff is instantly recognisable for its massive frame and heavily wrinkled, loose skin, combined with a calm but formidable guarding instinct.
What this means for your Neapolitan Mastiff
Hip and elbow dysplasia, bloat, and skin fold dermatitis, caused by moisture trapped in the breed's characteristic loose skin folds, are all significant considerations. Entropion and ectropion (eyelids rolling inward or outward) are also common given the breed's facial structure.
Regular cleaning of skin folds is especially important for this breed to prevent irritation and infection, and this becomes a routine worth keeping up throughout your dog's life.
When is a Neapolitan Mastiff considered a senior?
Under The Royal Kennel Club's size-adjusted guidance, giant breeds like the Neapolitan Mastiff are generally considered senior from around 5 dog years old.
