Ratings describe typical dogs of the breed on a 1–5 scale. Individual dogs vary with lines, upbringing and training.

Temperament

Neos are calm, steady and devoted to their families, often choosing one favourite person. They are gentle and affectionate with those they know.

They are natural guardians and suspicious of strangers. They can be dominant with other dogs. Socialisation from puppyhood and consistent training are essential, and they are best with experienced owners.

Living with a Neapolitan Mastiff

Exercise

Low to moderate: short daily walks and play. Avoid heat and strenuous exercise; Neos overheat easily.

Grooming

Weekly brushing, daily cleaning of skin folds and constant drool management. Keep nails short.

Training

Stubborn but sensitive; start early with short, positive sessions and consistent rules.

Kids & other pets

Loving with their own family; supervise with children because of size. Often best as the only dog.

Time alone

Tolerates moderate alone time but needs a cool, comfortable space and secure fencing.

Home fit

Best suited to a house with secure outdoor space; apartment living is hard on this breed and its neighbours.

Health

With good breeding and care, a Neapolitan Mastiff typically lives 7–9 years. These are the conditions most associated with the breed — not a prediction for any individual dog.

  • Eyelid problems and cherry eye

    Loose facial skin causes entropion, ectropion and cherry eye, often needing surgery.

  • Hip and elbow dysplasia

    Common in giant breeds; screened parents help.

  • Dilated cardiomyopathy

    A serious heart muscle disease; cardiac screening is recommended.

  • Skin fold dermatitis

    Deep folds trap moisture and bacteria; clean them daily.

  • Heat intolerance

    Neos overheat easily and need shade, water and air conditioning in warm weather.

Ask a breeder for

  • Hip and elbow evaluation
  • Cardiac examination
  • Eye examination

Cost to own

After the first year, expect roughly $2,000–$4,000 a year for food, routine vet care, preventives, insurance and supplies (US estimate).

  • Food, medication and anaesthesia are dosed by weight, so every vet visit costs more for a big dog.
  • Pet insurance for a puppy typically runs $30–$60 a month; premiums rise with age and breed risk.

History

The Neapolitan Mastiff descends from Roman war and guard dogs. For centuries mastiffs of this type guarded estates and farms around Naples in southern Italy.

After WWII, painter Piero Scanziani and other Italian enthusiasts worked to preserve and standardise the breed. The AKC recognised the Neapolitan Mastiff in 2004.
