About the Neapolitan Mastiff

Unless you’ve been to Jurassic Park, you’ve never seen anything like a Mastino. These majestic guardians of startling appearance are massive, powerful dogs. The U.S. Neapolitan Mastiff Club describes their dog’s head as “astounding”—and give them credit for hitting upon just the right adjective. The profuse hanging wrinkles and folds, and pendulous lips, make a Mastino look like a marzipan Mastiff that’s been out in the sun too long. And yet, the breed’s inner dignity and nobility can only be described as beautiful.

History

If Mastinos look like strange visitors from antiquity, it’s because that’s exactly what they are. The breed might go back as far as 700 b.c., with artifacts from several ancient civilizations depicting Mastino-like canines. In the Roman Empire, they found employment as war dogs, gladiators, and guardians whose bestial looks and huge frame were calculated to throw the fear of Jove into their adversaries. Today, those attributes are still terrifying enough to send an ill-willed intruder running for the hills.

Nutrition

Different dogs respond to different foods, and everyone has their own preference. In general any good-quality dog food is acceptable. The owner should keep an eye on the dog’s eyes, ears, nose and coat, and make sure the energy level is good. For the Neapolitan Mastiff, experienced breeders recommend food slightly higher in fat and lower in protein, especially when the dog is young, as they grow so fast. Do not supplement with calcium. Make sure that plenty of clean, fresh water is always available.

Grooming

The Neapolitan Mastiff is a short-coated breed, so in general a bath now and again is about all you need. The eyes and ears eyes and ears should be checked and gently cleaned whenever necessary with a damp cloth or paper towel. You will find that you need to keep a towel handy to dry the face and lips (and yourself!), especially after the dog eats or drinks. The Nails should be kept short—in fact, if you walk the dog for a mile or two twice a day on sidewalks or asphalt, he will keep his own nails short naturally.

Exercise

Every dog should have the opportunity to run and romp often, but don’t emphasize the running and quick turning, as joints can be easily damaged. This is a big, heavily built breed and can overheat easily, so be careful in warm weather. The Neapolitan puppy may want to play beyond when he should, so it is up to the owner to stop before the puppy gets too tired. Be careful about letting him going up and down stairs—many an exuberant puppy’s knee has been injured by a leap off a porch or a jump down those last few stairs. Breed experts do not recommend lots of tug-of-war games or violent wrestling, since the growing “mastino” will quickly learn he is stronger than his smaller human friend and think that he no longer needs to listen.

Training

While most adults of the breed are calm animals who sleep a lot, Neapolitan puppies are as active, curious, cute, and cuddly as the most winsome toy puppy. And many people find that the adolescent Neapolitan, when awake, is an energetic, powerful animal. It is important to train the Mastino when he is young, so that when dealing with the strong, stubborn teenage personality stage, the appropriate ruling structure is already in place. By the age of 3 or 4, most Neapolitans demonstrate desirable laid-back adult-type behavior. Neapolitans do not respond well to harsh training and need an encouraging and rewarding atmosphere. Be patient and consistent.

Health

Neapolitans are generally hardy dogs. One minor problem that often occurs is “cherry eye,” where tissue in the corner of the eye becomes red and inflamed. In the vast majority of cases, there is no permanent damage. Despite the breed’s impressive wrinkles and loose skin, most do not have skin problems. There are health problems that are common in giant dogs to which the breed is not immune. Bloat is a sudden, life-threatening condition that can affect all deep-chested breeds. Its causes are not fully understood, but owners should learn the signs that bloat is occurring and know what action to take. As with all breeds, the Mastino can also develop hip dysplasia. It is important to discuss any health concerns with the dog’s breeder and veterinarian.
