About the Neapolitan Mastiff

The Neapolitan Mastiff is a massive guardian breed from southern Italy, with loose skin, heavy wrinkles and a large head with pendulous lips and a prominent dewlap. Its short, dense coat can be grey, black, brown or tawny. It was developed as a guard of property and family, and has a slow, rolling gait. It needs an owner who understands very large dogs.

Temperament

Calm, watchful and devoted to family, it is typically wary of strangers and can be imposing. It needs early socialisation, gentle consistent training and an experienced owner.

Exercise

Exercise needs are modest, with short walks. Avoid strenuous exercise during growth and in heat.

Grooming

The Neapolitan Mastiff has a short, coarse coat that needs little more than a weekly rub down. Its heavy wrinkles and hanging lips are the main job: wipe and dry the folds daily and clean up drool, which gathers on the chest and walls.

Care & wellbeing

Giant breed joint care, careful feeding and avoiding obesity. Heat sensitivity and skin fold care are important. Lifespan is shorter.

History

An Italian guardian breed, with roots in the old molossoid dogs of the Roman world and kept in southern Italy as a protector of homes and property. Its heavy, wrinkled look was refined by breeders in the 20th century. It is a calm but imposing watchdog.

Health

The breed can be prone to

Health tests to ask a breeder about

  • Hip and elbow scores
  • Eye check
  • Heart screening

Not every Neapolitan Mastiff is affected, and this isn't a diagnosis. Read about common conditions and when to see a vet.

Cost to keep

Highest than average
  • Food, insurance and medicines cost more for a big dog
  • Little or no professional grooming needed
  • A 7–10 year commitment
  • Budget for breed-related health checks or insurance

A relative guide, not a price — costs vary a lot by country, insurer and lifestyle.

Is a Neapolitan Mastiff right for you?

Could suit

  • Calmer households and owners who prefer gentle walks
  • People who'd rather not spend much time grooming

Think twice if

  • This is your first dog — an independent breed can be a challenge to train
  • Space, food and vet costs are a concern — giant breeds need more of all three
  • You live somewhere hot or want a very active companion — flat-faced breeds can struggle with breathing and heat
