The most striking dog in the world, the Neapolitan Mastiff is the image of a living gargoyle, breathing and drooling. As if risen from the past, there is nothing comparable to the Neapolitan and its primitive approach to life as a domestic dog.
A massive animal, large boned, with an impressive appearance, the Neapolitan Mastiff has a large, wide head, with a well pronounced stop; large nose, deep lipped muzzle. The eyes are implanted forward and are quite round; the ears are small, and the neck is robust and very muscular – the dewlap reaches the nape of the back. Shoulders long and slightly sloped; wide chest, straight upper outline; wide kidneys; long and wide femur; moderately lengthed tibia; powerful hocks; the hind feet open slightly. The tail is thick at the root, narrowing to the tip, normally docked to a third. The coat is short and thick, rough in texture, with equal length and evenly smooth, without bristles. The colors cover grey, dark grey and black; brindles are admitted in every color; a small spot on the chest and over the fingers is admitted. The Neapolitan stands from 65 to 75 cm for males and from 60 to 68 cm in females, and weighs between 60 and 70 kg the males and from 50 to 60 kg in females.
“How cute” you say? Perhaps. This little charm will grow you out of your home and then it will eat the house. Keep the Neapolitan outside to prevent it from remodeling the home. 
The Neapolitan Mastiff is a strong dog, a large and strong dog, which is not the typical family dog. The ideal Neapolitan is devoted to a single person. It is larger and stronger than you – only apt for a dominant and experienced owner -. The Neapolitan is too large to play with children, and a smart child will automatically give a step back when he or she sees these 70 kg coming down the hill. The Neapolitan is clumsy: clumsy when eating, clumsy when playing, clumsy as a dog; it is best to keep it outside, and if it is inside the house, consider adapting your home insurance or selling anything of value it might destroy. The Neapolitan can’t climb the stairs, but it loves to eat the wooden details. Keep in mind that the Neapolitan was bred for protection work, and that it tends to reduce an opponent by instinct. Only to its master, the Neapolitan is very loyal, and it is like a child and unpredictable. Make no mistake, the well trained Neapolitan loves children and at the same time it continues being an instinctive guardian.
The Neapolitan, of course, is a very large dog. After eight weeks, it weighs an average of 10 to 15 kg. It is also very compactly built, for which every half a kilo seems 750 g. It grows quickly: the puppy should not be overfed, since an excessive weight before time will lead to bone and joint problems. Maturity is not reached until after two years. The interested party should take its time to study and know the breed before purchasing. Be careful, since the Neapolitan’s popularity has led to many opportunist breeders. The buyer should see the parents: an adorable puppy could turn into a monstrous adult. The puppy needs socialization, since the Neapolitan is introverted. No Neapolitan moves gracefully, no matter the age. The puppy can limp between the fourth and sixth months, due to loose ligaments – give it an aspirin – it will overgrow this phase. Adolescence is marked for the awakening of a strong dominance inherent to the breed. Up to the fourth month the puppy urinates indiscreetly, and needs plenty of water to avoid dehydration.
Thinking about a Neapolitan? Think hard. Consider that you will consult with your veterinarian, insurance company, psychiatrist, and someone who survives living with one of these fabulous, tempting monsters. And then read this chapter again. 
The powerful Neapolitan demands care from its owner, not lastly, hygiene. The Neapolitan is notably clumsy when eating and soils everything. The owner should wipe its face after every meal, as a mother with her one-year-old. The abundant loose skin and creases in the breed demand cleanliness and frequent baths – don’t worry about drying the skin too much -. The breeder’s larges concerns of course are orthopedic in type, especially hip and elbow dysplasia, osteochondrosys and arthritis. As for diet, the Neapolitan needs a high percentage of carbohydrates and fat, less protein, more vitamins and minerals. Dry food is not recommendable for adequate growth. The puppy only needs moderate exercise, and strong impact activities should be avoided, since the young Neapolitan has a very “loose” build. It is known that young specimens and adults can suffer nephritis, if they endure too much cold. The Neapolitan dies from heat and humidity – shade and water are absolutely essential to their survival -. I should be wetted regularly in heat times. According to breeder-veterinarian Sherilyn Alien, the Neapolitan Mastiff has a low thyroid hormone level, which can lead to muscular weakness, rigidity, cardiomiopathy, incongruent bone growth, recurrent skin problems and a torsion prone gastric and intestinal function. The low thyroid level is characteristic to the breed, and responsible for its unusual appearance: a thyroid stimulating therapy can correct these problems, but will make you dog resemble this majestic living gargoyle relic less. Who needs Frankenstein when you can live with a Neapolitan?
