What Makes Neapolitan Mastiffs Special

The Neapolitan Mastiff is an awe-inspiring dog of immense size and power. Characterized by heavy, loose skin that forms dramatic wrinkles and folds, their appearance is unique and unforgettable.

Beneath the formidable exterior lies a loyal and peaceful companion, devoted to its family. They are natural guardians, watchful and silent, preferring to intimidate rather than attack.

Neapolitan Mastiff History & Origin

Descended from the ancient molossus dogs of Rome, the Neapolitan Mastiff is a historic guardian of family and property in southern Italy. These giant war dogs were refined over centuries for their formidable appearance and protective nature.

The breed's ancestors can be traced back to the giant war dogs used by the Roman army.

After the fall of the Roman Empire, they survived in the Neapolitan countryside, where they were bred as estate guards.

The breed was rediscovered and standardized in Italy after World War II, with the first dogs being exhibited in Naples in 1946.

The Neapolitan Mastiff gained recognition from the AKC in 2004.

A Neapolitan Mastiff named 'Fang' was featured in the Harry Potter movies, increasing the breed's visibility.

Due to their specialized needs, prospective owners should expect to pay a significant amount, often $2,500 to $4,000, from a reputable breeder. Adoption is a less common but possible option.

Neapolitan Mastiff Appearance

The Mastino is a head-turning breed, defined by its massive build and profusely wrinkled head. They carry themselves with a noble, majestic bearing.

Their short, dense coat comes in solid colors like black, blue, and various shades of grey and fawn. Their gait is slow and bear-like, reflecting their heavy structure.

Physical Features

Ears

Their ears are triangular, set high on the skull, and hang flat. They are small in proportion to the massive head.

Eyes

The eyes are deep-set and almost hidden by the heavy facial wrinkles. They convey a steady, watchful expression.

Nose

The nose is large and spongy with open nostrils. The color of the nose leather corresponds to the coat color.

Coat & Build

Coat Length

The Neapolitan Mastiff has a short, dense, and hard-textured single coat.

Coat Color

The American Kennel Club (AKC) standard colors include black, blue, grey, mahogany, and tawny, with brindle markings also acceptable. Small white markings on the chest and toes are permitted.

Tail

The tail is thick at the base and tapers to a point. It is often docked for working dogs in countries where it is permitted, but the natural tail is carried up and over the back.

Neapolitan Mastiff Temperament

Despite their intimidating appearance, Neapolitan Mastiffs are steady and loyal dogs, deeply devoted to their family. They are naturally watchful and protective, making them excellent guardians of the home.

The Mastino is generally calm and quiet unless provoked. They are wary and reserved with strangers, a testament to their guarding instincts. Early and thorough socialization is crucial to ensure they are well-adjusted.

With their loved ones, they can be affectionate and even silly, often unaware of their massive size when trying to be a lap dog. They thrive on companionship and want to be a part of the family.

This is not a breed for a novice owner. Their strong will, massive size, and protective nature require an experienced handler who can provide firm, consistent training and leadership.
