Plan the full cost of a puppy in its first year.
A puppy's first year carries costs no adult dog repeats: a three-stage vaccination course, neutering and the socialisation classes that determine how manageable the next decade will be. Those sit alongside the purchase price as one-time spending, while food and insurance form the running cost that continues for life. The weekly figure is the one that catches people out — a total that reads as manageable annually often looks very different expressed as a standing weekly commitment.
Puppy first-year budget
First year = purchase price + (vaccinations + neutering + training) + (monthly food + insurance) x 12
It is the highest-leverage line in the list. Behavioural problems are the leading reason dogs are surrendered, and a few hundred spent on classes in the first six months is far cheaper than remedial behaviourist work later.
It usually costs less, not more — premiums rise with age and after claims. Insuring before any condition is diagnosed is what keeps a policy comprehensive, since pre-existing conditions are excluded on later applications.
Substantially. Large breeds eat two to three times as much and carry higher insurance and medication costs, so a giant breed's running cost can double the monthly figure here.
