Neapolitan Mastiff Origin And History

The Neapolitan Mastiff is an ancient breed of dog with an extremely long and interesting history. Its ancestors have seen wars and battles going back to the era of Alexander the Great, who is known for conquering the known world of his time.

Molosser dogs of Asia, the Middle East, and Northern Africa, the Neapolitan Mastiff’s ancestors, were brought to Greece in 300 BC by the conqueror and later saw use by the Roman Empire as war dogs when they invaded and conquered the area.

Sometime later, the Roman Empire launched an invasion against England and bred their mastiff type with the English Mastiff, and this led to the creation of the earliest version of this breed. The Neapolitan Mastiff also saw a lot of combat outside of the battlefield. It was often pitted against lions, elephants, tigers, bulls, jaguars, and even men. They even fought in Roman arenas like gladiators.

As things changed and civilization moved forward, the Neapolitan Mastiff was able to thrive in the Neapolitan region of Italy as protectors of family homes, owners, and property. However, the Mastiff breed of dog came to near extinction as a result of World War II. Since then, the breed has rebounded in popularity and came back from the brink of extinction.

The Neapolitan Mastiff (nicknamed the Mastino) is not a difficult breed of dog to pick out of a lineup. It has an unmistakable appearance with its large and imposing size and the noticeable wrinkles and folds in its skin that provides its fearsome appearance.

Its head is no different.  The Neapolitan’s head is large with wrinkles and a droopy appearance with folds coming over and under its eyelids. While its ears are traditionally cropped short, they inherently have medium-length ears that hang over with a triangular shape.

As far as its body goes, it is longer than it is tall and underneath all of those folds of skin. It is also characterized by its broad and very muscular chest and legs and retains a thick bone structure. The Neapolitan Mastiff also has a short coat of fur that will be found in colors of tawny, mahogany, blue, and black.

In terms of popularity, the Blue Neapolitan Mastiff is the most popular of the breed and is followed behind by the Black Neapolitan Mastiff. There are also Neapolitan Mastiffs that are brindle in color but are not referred to as Brindle Neapolitan Mastiffs. They can also have white markings on their chest and toes, according to the AKC (American Kennel Club.)

Neapolitan Mastiff Temperament And Personality

A properly trained Neapolitan Mastiff will quickly and appropriately deal with a threat to its owners and home.

A potential problem with the Neapolitan Mastiff is that it may be a bit aggressive and overly protective of its owners if it is not trained properly and socialized.

Neapolitan Mastiffs And Kids

The subject of Neapolitan Mastiffs and children can be a difficult situation to address. On the one hand, the Neapolitan Mastiff is known to be extremely sweet and caring with those they consider to be a part of their pack. That includes the adults and children within that pack.

One thing to pay attention to, however, is the size of the Neapolitan Mastiff, as they may accidentally knock over a small toddler or baby without realizing it. With this in mind, it is important to supervise your children when they are around the Mastiff if you have small children in the home.

Are Neapolitan Mastiffs Good Around Other Dogs & Pets?

The Neapolitan Mastiff is a territorial and jealous dog. Not only do they tend to become jealous of children if they feel like they are not receiving the same amount of attention, but they will also become jealous of other dogs or animals within the home under the same circumstances.

The Neapolitan Mastiff is capable of getting along with other pets in the home fine if they are socialized from puppy age to be around other animals, but even with socialization, they may tolerate the other dog or animal. They are not going to be best friends by any means. It is recommended for this breed of dog to be in a “one pet household” if it is possible.

Training the Neapolitan Mastiff

While they are sweet and gentle with the members of their pack, Neapolitan Mastiffs need to be socialized and receive obedience training as soon as possible to prevent unnecessary aggression with other dogs and strangers. When training the Neapolitan Mastiff, you need to establish yourself as the alpha of the pack for it to take to the training.

When putting your Mastiff through socialization and obedience training, it is important to give them something to stay focused on, like making eye contact. Neapolitan Mastiffs, like all Mastiffs, communicate primarily through eye contact, and it will let them know your attitude towards them since they strive to keep their owners happy.

Also, it is important to be kind and gentle throughout the training and offer them rewards and praise for performing well when training the Neapolitan Mastiff. Refrain from raising your voice as they are sensitive dogs, and this can slow down the training process. Training sessions need to be short, as well. If they are too long in duration, Neapolitan Mastiffs will lose interest and fall asleep.

Proper Housing for the Neapolitan Mastiff

Despite its large and imposing size among dogs, the Neapolitan Mastiff is not a dog breed that you get as an outside dog. They prefer to be indoors and are completely fine with living in an apartment. If you think that you need to have a big house and a large yard for your Neapolitan Mastiff, you would be wrong. Neapolitan Mastiffs are not the most active of dogs and don’t require such an open space.

When it comes to letting the Neapolitan Mastiff outside to handle its “business” and stretch out those legs of theirs, it is best only to do that if you happen to have a fenced yard. This is due to them being protective of their owners and their home, and any passing individual can get bitten if they come too close to the home.

If you happen to live out in the countryside and don’t have neighbors for a bit of distance, this is not going to be an issue, and you don’t have to worry about your Neapolitan Mastiff running off either. They tend to stick close to the home and will not wander off.

One thing to keep in mind, this is not a dog you want to have if you are a clean freak. Mastiffs are not hypoallergenic, and they will shed. Aside from that, they drool a lot from those big, pendulous lips of theirs. If they shake their head, you can be sure that there is going to be slobber raining down wherever they may be. If that bothers you, you should look at a different breed of dog for your home.

Neapolitan Mastiff Exercise Requirements

The Neapolitan Mastiff, like all other Mastiffs, are not very active dogs by nature and do not require very much physical activity to maintain their health; however, they can benefit both physically and psychologically from a little bit of play and short walks.

When you are walking the Neapolitan Mastiff, try not to exceed more than a mile when walking them. A general rule of thumb, when it comes to Mastiffs, is to avoid walking them farther than you can carry them. They do not enjoy strenuous running and playing, and it does the breed more harm than good by trying to push them to exercise too hard.

The reason why you don’t want to push them too hard by taking long walks is that the Neapolitan Mastiff will lie down wherever it feels like when it gets too tired or too hot. If you don’t want to carry the extremely large dog a long way back home, try keeping an eye as to how far you walk and don’t walk farther than you can carry the dog, if you need to.

When it comes to Mastiff puppies, do not exceed walking them more than three blocks and don’t allow them to run up and down stairs or jump from great heights. This can be detrimental to their health in the long run and is considered unsafe for this breed of dog.
