NEAPOLITAN MASTIFF BREED STANDARD
Origins
The Neapolitan Mastiff originates from Italy and is an ancient mastiff-type breed traditionally associated with guarding homes, estates and property.
The modern breed became particularly associated with the Naples region of southern Italy, where these powerful dogs were valued for their imposing appearance, courage and natural guarding ability.
Following the Second World War, dedicated Italian breeders worked to preserve and establish the Neapolitan Mastiff as a recognised breed, retaining its characteristic massive head, substantial bone, loose skin and powerful construction.
The Neapolitan Mastiff should remain an imposing and unmistakable guardian while retaining the soundness, mobility and physical ability expected of a functional working mastiff.
General Appearance
The Neapolitan Mastiff is a large, powerful and imposing mastiff, possessing substantial bone, heavy musculature and unmistakable breed type.
The head should be massive and broad, with characteristic loose skin and wrinkles, while the body remains strong, balanced and physically capable.
The overall impression should be of great strength and substance without excessive weight, skin or exaggeration that interferes with vision, breathing, movement or general function.
Despite its size and powerful construction, the Neapolitan Mastiff should remain sound, mobile and capable of purposeful movement.
Breed type should come from correct structure, substance, head type and characteristic skin rather than exaggeration.
Size & Proportions
The Neapolitan Mastiff is a large, substantial and heavily built breed.
Males should stand approximately 26–30 inches (65–75 cm) at the shoulder, with females approximately 24–27 inches (60–68 cm).
The body should be slightly longer than the height at the withers, creating a powerful, substantial outline without appearing excessively long or low.
Bone and muscle should be considerable, with males generally appearing larger, heavier and more masculine than females.
Great size and substance are characteristic of the breed, but excessive weight or bulk that compromises balance, movement or physical ability is undesirable.
Correct proportion, sound construction and overall function should take priority over excessive size or weight.

Head & Muzzle
The head should be large, broad, deep and powerful, appearing massive in proportion to the body and forming one of the defining characteristics of the breed.
The skull should be broad and substantial, with well-developed cheeks and a clearly defined stop. Characteristic wrinkles and folds should be present across the head and muzzle without excessive skin obscuring the eyes or interfering with normal function.
The muzzle should be broad, deep and strong, approximately one third of the overall head length, with powerful jaws and good width through to the nose.
The muzzle should never appear narrow, weak or excessively shortened. Head size and wrinkle should not compromise breathing, vision, eating or normal movement.
Nose & Breathing
The nose should be large, broad and well developed, with wide, open nostrils appropriate to the colour of the coat.
Breathing should be free, quiet and effortless at rest, with sufficient width through the muzzle and nasal passages to allow normal airflow.
The characteristic heavy head, loose skin and wrinkles must not obstruct the nostrils or interfere with normal breathing.
Pinched or restricted nostrils, persistent noisy breathing, laboured breathing or any exaggeration that compromises respiratory function are undesirable.

Skin & Wrinkles
Loose, thick skin and characteristic wrinkles are an important feature of the Neapolitan Mastiff and should contribute to the breed’s unmistakable appearance.
Wrinkling should be most evident across the head, muzzle and neck, with naturally loose skin also present over the body.
The skin should remain healthy and manageable. Excessive folds that obscure the eyes, restrict movement, interfere with breathing or create persistent skin and hygiene problems are undesirable.
The aim should be characteristic Neapolitan Mastiff skin and wrinkle without exaggeration that compromises the dog’s comfort or function.
Eyes
The eyes should be clear, healthy and well set, giving a calm, confident and watchful expression.
They should be proportionate to the head and neither excessively prominent nor deeply sunken.
Eye colour should complement the coat, with darker shades generally preferred.
Loose skin and wrinkles around the head must not obscure the eyes, cause irritation or interfere with normal vision.
Excessive exposed eye tissue, persistent irritation or eyelid construction that compromises eye health is undesirable.

Ears
The ears should be relatively small in proportion to the massive head, set high and naturally carried close to the cheeks.
Natural drop ears should complement the broad, powerful shape of the head without appearing excessively large or heavy.
The ears should be healthy, correctly formed and free from exaggeration.
Cropped ears are not accepted.
Body & Condition
The body should be large, powerful and heavily muscled, with substantial bone, a broad deep chest and well-sprung ribs.
The back should be strong and well supported, with the body slightly longer than the height at the withers and balanced throughout.
The Neapolitan Mastiff should carry considerable substance while remaining fit and physically capable. Size and weight should come from correct structure, bone and muscle rather than excessive body fat.
A visible waist and appropriate abdominal tuck should remain present beneath the breed ’s naturally loose skin.
Excessive weight, bulk or loose skin that restricts movement or disguises poor physical condition is undesirable.
CONSTRUCTION DIAGRAM
Front Construction
The front should be broad, powerful and strongly constructed, reflecting the considerable size and substance of the breed.
The chest should be wide and deep, with strong, muscular shoulders and substantial bone throughout the forequarters.
The forelegs should be straight, strong and well positioned beneath the body, providing a stable and balanced base for the dog’s weight.
Width and substance should not be exaggerated to the point that the elbows are forced outward or normal movement becomes restricted.
The overall construction should provide strength, stability and sound, purposeful movement.
Feet
The feet should be large, strong and compact, providing a stable base for the breed’s considerable size and weight.
Toes should be well formed and naturally arched, with strong pads and good overall structure.
The feet should point naturally forward and remain firm and stable during movement.
Weak, flat, excessively splayed or severely turned feet are undesirable.
CONSTRUCTION DIAGRAM
Rear Construction
The rear should be strong, broad and powerfully muscled, providing the drive required to move the breed’s substantial body with ease.
The thighs should be well developed, with strong bone and balanced angulation through the hindquarters.
The rear legs should stand firmly beneath the body, with strong hocks and a stable, balanced stance.
Viewed from behind, the hindquarters should remain strong and reasonably parallel during movement.
Weak or narrow hindquarters, poor muscle development, excessive straightness or over-angulation that compromises stability and movement are undesirable.
Movement & Athletic Ability
Movement should be powerful, balanced and purposeful, with good reach from the front and strong drive from the rear.
Despite its considerable size, heavy bone and substantial build, the Neapolitan Mastiff should remain mobile, athletic and physically capable.
A correctly constructed dog should be able to walk, run, play and exercise freely, possessing the strength, stamina and agility expected of a functional guardian breed.
Movement should remain steady and efficient, with the dog carrying its weight comfortably and without excessive rolling, weakness or restriction.
Excessive size, weight, skin or structural exaggeration that results in cumbersome, laboured or restricted movement is undesirable.
CONSTRUCTION DIAGRAM
Tail
The tail should be broad and strong at the base, gradually tapering towards the tip and set naturally as a continuation of the body.
At rest it should hang down and reach approximately to the hock, rising naturally when the dog is alert or moving without being carried tightly over the back.
The tail should be naturally formed, freely movable and contribute to the dog’s balance during movement.
Excessively short, tightly curled, kinked or deformed tails are undesirable.
Coat
The coat should be short, dense, smooth and close-fitting to the body.
It should appear healthy and naturally glossy, allowing the powerful muscular outline of the dog to remain clearly visible.
Long, woolly, feathered or excessively sparse coats are undesirable.
CONSTRUCTION DIAGRAM
Colour
Accepted colours include grey, blue, black, mahogany, tawny and fawn, including brindle variations of these colours.
Small white markings on the chest and toes may be accepted, but extensive white markings are undesirable.
No accepted colour should be preferred over another.
Colour should always remain secondary to correct breed type, structure, health, temperament and physical ability.
Temperament
The Neapolitan Mastiff should be confident, courageous, calm and devoted to its family. Naturally watchful and protective, the breed should possess a strong guarding instinct and remain alert to its surroundings without displaying unnecessary aggression. The ideal temperament is steady, self-assured and dependable, with the confidence to stand its ground when required. Early socialisation, clear boundaries and consistent training are essential due to the breed’s considerable size, strength and natural guarding instincts. Excessive nervousness, instability or unprovoked aggression are undesirable.
