A Neapolitan Mastiff typically lives 8–10 years. Most of what determines whether it gets there is routine care rather than anything dramatic.
Planning for about 9 years
A Neapolitan Mastiff is with you for about 9 years. Budget and routine both need to survive that, including the last quarter of it when a giant dog needs more veterinary attention than it did young.
What to watch for in a giant dog
For this size class: weight gain and hip health. None is a reason not to own the breed; all are cheaper to manage early.
What “protective” means day to day
The Neapolitan Mastiff is described as protective, calm, loyal. Of those, protective is the one that shapes an ordinary day most. It is easy to read as a selling point and harder to live with than the word suggests, because it does not switch off when you are busy.
Balancing protective against calm
Breeds described as both protective and calm need the two managed together rather than separately. With a giant dog that usually means a predictable routine first and training second - the routine is what makes the training stick.
A breed from Italy, living in India
The Neapolitan Mastiff was developed in Italy. The part that travels badly is rarely temperament - it is the coat and the tolerance for heat. Plan the year around that and most of the rest follows.
Keep the records
Booster schedules run from the original dates, and a new vet asks for the history first.
Vaccination and deworming
The core course starts around six weeks, rabies follows, then annual boosters. Deworming runs fortnightly to twelve weeks, monthly to six months, then quarterly.
