Neapolitan Mastiff Puppy Weight Calculator

Common health concerns include entropion and ectropion (eyelid problems that require surgical correction), cherry eye, gastric torsion or bloat (a life-threatening emergency), dilated cardiomyopathy, Wobbler syndrome (spinal compression), hypothyroidism, epilepsy, and bone tumors such as osteosarcoma. The average life expectancy is only seven to nine years, which is typical for giant breeds.
To protect your puppy, choose a responsible breeder who performs health screenings, and schedule regular veterinary check‑ups.
Joint laxity due to rapid growth

Because this breed grows rapidly, you should give three meals per day until six months of age, then reduce to two meals daily.
Measure portions carefully, as excess weight stresses the growing skeleton.
Do not allow your puppy to become overweight, and avoid free‑choice feeding. Never supplement with additional calcium unless directed by your veterinarian.

Neapolitan Mastiffs need minimal maintenance, with a strong emphasis on brushing their short coat once a week and washing their skin folds every day to prevent infections.
Monthly bathing for delicate skin, frequent ear cleanings, and regular slobber control are important requirements. They shed more in the spring and fall and are moderate shedders.
Their short coat needs brushing only once or twice per week using a soft brush, rubber curry brush, or grooming mitt to manage shedding.

Avoid intense running or jumping during puppyhood. Their heavy bodies and growing joints are vulnerable to damage.
Focus on moderate, low-impact activities such as short walks and playtime on soft ground. Expose your puppy to various people, children, calm dogs, and different environments during the early socialization period to prevent fearfulness or excessive guarding.
Controlled exercise helps strengthen muscles and reduce the risk of obesity. House training is usually straightforward with a consistent schedule and crate training.
