About

Ensuring your pet receives their vaccinations on time is the single most effective way to prevent fatal diseases like Parvovirus, Distemper, and Rabies. However, the schedule varies significantly depending on the age of the animal and whether it is a cat or a dog.

This tool generates a chronological timeline for the 'Core' vaccines - those considered vital for all pets regardless of lifestyle. It calculates the critical 6, 9, 12, and 16-week milestones for puppies and kittens, ensuring you don't miss a booster shot that could leave your pet's immunity gap open.

Formulas

The schedule is calculated by adding weeks to the birth date (D_birth):

1st Round: D_birth + 8 weeks
2nd Round: D_birth + 12 weeks
3rd Round: D_birth + 16 weeks
