A Great Dane Puppy typically lives 7–10 years. Most of what determines whether it gets there is routine care rather than anything dramatic.
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.
The annual check
Once a year for an adult dog, and book it before the hot months rather than during them.
What “friendly” means day to day
The Great Dane Puppy is described as friendly, patient, dependable. Of those, friendly 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.
Planning for about 8 years
A Great Dane Puppy is with you for about 8 years. Budget and routine both need to survive that, including the last quarter of it when a medium dog needs more veterinary attention than it did young.
Keep the records
Booster schedules run from the original dates, and a new vet asks for the history first.
A breed from Global / Various, living in India
The Great Dane Puppy was developed in Global / Various. 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.
Balancing friendly against patient
Breeds described as both friendly and patient need the two managed together rather than separately. With a medium dog that usually means a predictable routine first and training second - the routine is what makes the training stick.
