Today, the Neapolitan Mastiff is still a popular breed in Italy, where it is known as the Mastino Napoletano. These dogs are often used as guard dogs and are highly valued for their loyalty and protective nature. They are also beloved companions and make excellent family pets.

The Neapolitan Mastiff gained recognition by the Italian Kennel Club in 1949, and the breed was officially named the Mastino Napoletano. In 1973, the breed was recognized by the American Kennel Club, bringing it to the attention of dog lovers in the United States. Since then, the breed has grown in popularity and is now a favorite among dog enthusiasts worldwide.

In conclusion, the Neapolitan Mastiff has a rich and fascinating history that spans thousands of years. From its origins as a gladiator dog in ancient Rome to its current status as a beloved companion and guard dog, the Neapolitan Mastiff has captured the hearts of dog lovers around the world.

Physical Characteristics and Appearance

The Neapolitan Mastiff is a large and imposing breed, with males weighing between 150 to 200 pounds and standing 26 to 30 inches tall at the shoulder. Females are slightly smaller, weighing between 110 to 150 pounds and standing 24 to 29 inches tall. Their massive heads, droopy jowls, and wrinkled skin make them one of the most recognizable dog breeds.

Size and Weight

As mentioned earlier, the Neapolitan Mastiff is a giant breed. Their size and weight make them an excellent choice for families looking for a large and robust dog. However, their size also means that they require a substantial amount of space and exercise to prevent obesity and other health issues.

Coat and Colors

The Neapolitan Mastiff has a short and dense coat that comes in various colors, including black, blue, mahogany, and tawny. The fur is easy to maintain, and brushing once a week is sufficient to keep the dog’s coat healthy and shiny.

Distinct Facial Features

The Neapolitan Mastiff has some unique facial features, including its signature wrinkles and droopy jowls. The wrinkles are more pronounced in puppies and become more defined as the dog grows older. The droopy jowls serve a practical purpose, as they help the dog’s mouth retain saliva, which can come in handy during a fight or a confrontation with an intruder.

Temperament and Personality Traits

Beyond its intimidating appearance, the Neapolitan Mastiff is a gentle and affectionate breed. They are loyal to their owners and are known to be protective of children. They have a calm and laid-back temperament, but they can also be protective and territorial.

Despite their size and strength, Neapolitan Mastiffs are known for their gentle nature and make great family pets. They are patient and tolerant of children and will often be found lying next to their owners, providing comfort and companionship.

Loyalty and Protective Instincts

The Neapolitan Mastiff is a breed that is fiercely loyal to its owners. They will protect their family at all costs and will be a constant companion to their owners. Their protective instincts make them great guard dogs or watchdogs, as they are always on alert for potential threats.

While their protective nature is a desirable trait for many owners, it’s important to ensure that they are properly trained and socialized to prevent any aggressive behavior towards strangers or other animals.

Intelligence and Trainability

The Neapolitan Mastiff is an intelligent breed that is willing to please its owner. They are quick learners and respond well to positive reinforcement training methods.

However, due to their independent nature, they can be stubborn and may require consistent training and patience. Early socialization with other dogs and animals is crucial to prevent aggression or dominance issues later in life.

Neapolitan Mastiffs excel in obedience training and can be trained to perform a variety of tasks, such as therapy work or search and rescue operations.

Socialization and Interaction with Other Animals

The Neapolitan Mastiff can be friendly towards other animals if they are socialized at an early age. They are naturally protective of their family and may become territorial towards other dogs, especially of the same sex.

It’s important to supervise their interactions with other dogs and animals, especially during the early stages of their training. With proper socialization and training, Neapolitan Mastiffs can coexist peacefully with other pets.

However, due to their high prey drive, they may be prone to chasing smaller animals, such as cats or rabbits. It’s important to keep them on a leash or in a secure area when around smaller animals.

Overall, the Neapolitan Mastiff is a loyal and affectionate breed that requires proper training and socialization to reach its full potential. With patience and consistency, they make great family pets and loyal companions.

Health and Lifespan

Like all breeds, the Neapolitan Mastiff is prone to certain health issues that owners should be aware of. With proper care and attention, however, the breed can live a long and healthy life.

Common Health Issues

Some of the most common health issues that affect the Neapolitan Mastiff include hip dysplasia, elbow dysplasia, bloat, and skin infections. As with most large breeds, the Neapolitan Mastiff can develop joint issues, so regular exercise, a healthy diet, and regular checkups are essential to prevent mobility problems later in life.

Preventative Care and Regular Checkups

To keep your Neapolitan Mastiff healthy, it’s essential to provide preventative care, such as annual checkups, vaccinations, and parasite control. Regular exercise, a healthy diet, and a good grooming routine can also help to prevent health issues. Always consult with your veterinarian if you notice any unusual behavior or symptoms, as early detection and treatment can prevent more severe health issues down the line.

Expected Lifespan

The expected lifespan of a Neapolitan Mastiff is between 8 and 10 years. However, with proper care and attention, the breed can live longer than ten years.


All in all, the Neapolitan Mastiff is a beautiful and imposing breed that makes for a loyal and protective companion. These dogs require proper care and attention to ensure they live happy and healthy lives. Whether you are looking for a guard dog or a family companion, the Neapolitan Mastiff is an excellent choice for anyone looking for a big dog with a big heart.
