The dates generated here are an educational estimate based on general guidelines. Your puppy's actual protocol may change based on where you live, local rabies regulations, the animal's health history, exposure to other pets, the vaccine/dewormer product used, and the responsible veterinarian's clinical decisions. Always confirm and adjust the dates with a veterinarian before following them.

How the calculation works

The vaccination schedule follows the WSAVA (World Small Animal Veterinary Association) 2024 guidelines: the first dose of core vaccines is given between 6 and 8 weeks of age, with additional doses every 2 to 4 weeks until at least 16 weeks — this is because the immunity a mother passes to her puppies (maternally derived antibodies) varies between litters and can neutralize the vaccine if it's given too early.

WSAVA also recommends a booster between 6 and 12 months of age (we use 26 weeks in this schedule) to fully immunize puppies who still had maternal antibody interference at the last dose of the initial series. The rabies vaccine is typically allowed starting at 12 weeks of age, but the exact age depends on local regulations and the vaccine manufacturer.

Deworming follows a standard protocol widely used by veterinarians: the first dose at 15 days of age, repeated every 15 days until 3 months old (to break the reinfestation cycle from worms transmitted through mother's milk), and then monthly doses until 6 months old. After that, the ideal frequency depends on the animal's lifestyle and should be set by the veterinarian.

You can download the whole schedule as an .ics file, importable into Google Calendar, Apple Calendar, or Outlook, to get automatic reminders for each dose.

Frequently asked questions

What happens if I delay a vaccine or deworming dose?

A short delay of a few days usually doesn't invalidate the schedule, but longer delays can leave the puppy unprotected during the window when maternal immunity has already dropped and the vaccine hasn't fully taken effect yet. If a dose is delayed significantly, the protocol may need to be restarted or adjusted — talk to your veterinarian as soon as you notice the delay, instead of simply giving the next dose on the original date.

Is the rabies vaccine mandatory?

In many places, rabies vaccination is required by law and is part of public health campaigns, since rabies is a fatal zoonotic disease. The minimum age for the first dose varies by local regulation and by manufacturer — usually from 12 weeks of age — so confirm the rule where you live and the product used with your veterinarian.

Does a puppy rescued from the street need different care?

Yes. Puppies of unknown origin tend to have a higher parasite load and a greater risk of prior exposure to infectious diseases, so the veterinarian may recommend more frequent deworming, additional tests (such as screening for distemper, parvovirus, or FIV/FeLV), and adjustments to the start of the vaccination schedule before following the standard calendar. Don't skip the initial clinical evaluation in these cases.

Can I vaccinate and deworm on the same day?

Yes, vaccines and dewormers act differently in the body and can usually be given on the same day without issue — in fact, the schedule generated here shows doses that fall on the same date. That said, the veterinarian may prefer to space them out by a few days if the puppy has low immunity, is sick, or is very weak.

When is my puppy fully protected to go out on walks?

Full protection against core diseases is only considered established about 1 to 2 weeks after the last dose of the initial series (usually around 16 weeks of age). Until then, avoid contact with animals of unknown vaccination status and high-risk environments (busy dog parks, pet stores, kennels), but controlled socialization in safe environments can and should start before that, following your veterinarian's guidance.
