Dog Vaccination Schedule: What's Core, What's Required, When

Vaccines are one of those things you simply don't put off. They protect your dog from diseases that used to wipe out whole litters, and in the case of rabies, they're a legal requirement in Poland. Below you'll get a clear picture of what you're protecting your dog against and roughly how the schedule works. The exact timeline is always set by your vet, because it depends on age, region and your dog's lifestyle.

What do core vaccines protect against?

Core vaccines are the ones vets recommend for every dog, whether it roams the forest or mostly circles the block. They guard against diseases that are dangerous, easily spread and often deadly.

Disease	What the vaccine protects against
Distemper	A viral disease attacking the respiratory, digestive and nervous systems. Often fatal, especially in puppies.
Parvovirus (parvo)	A highly contagious virus causing bloody diarrhoea and vomiting. Brutal in puppies, and the virus survives a long time in the environment.
Infectious hepatitis (adenovirus)	Viral damage to the liver and other organs. Included in standard combination shots.
Leptospirosis	A bacterial disease spread through rodent urine and contaminated water. Threatens the kidneys and liver, and can pass to humans.
Rabies	A fatal viral disease of the nervous system, dangerous to people too. In Poland the vaccine is legally required.

Most of these go in a single combination shot - one injection protects against several viruses at once. Rabies is usually given separately.

Is the rabies vaccine required?

Yes - and this is the single most important legal fact in the whole topic. In Poland, vaccinating your dog against rabies is mandatory. The dog must be vaccinated within 30 days of turning 3 months old, then repeated at least every 12 months from the last dose.

A few things worth keeping in mind:

• Only a licensed vet can give the shot, and it must be recorded in the dog's documentation or passport.
• The requirement applies to every dog, even one that rarely goes out.
• Skipping it can lead to a fine.

This isn't paperwork to dodge. Rabies is fatal and dangerous to humans too, which is why the law treats this shot as a requirement, not a suggestion.

What does a puppy vaccination schedule look like?

Puppies are born with some immunity from their mother, and it fades over time. That's why vaccines aren't a one-and-done shot but a series, timed so that vaccine immunity takes over exactly as the mother's protection wears off.

The general pattern usually goes like this:

1. First dose around 6-8 weeks of age - the start of the core vaccine series.
2. Follow-up doses every few weeks - repeated until the puppy builds full immunity, typically through the early months.
3. Rabies vaccine - given on the timeline the law requires, no later than 30 days after the dog turns 3 months old.
4. Adult boosters - at intervals your vet decides.

You don't set the exact dates and intervals yourself. The numbers above are rough guardrails, not a prescription. The real schedule is chosen by your vet based on your dog's age, the product used, the disease situation in your region and lifestyle. Until the core series is finished, it's wise to avoid contact with unknown, unvaccinated dogs and high-traffic animal spots.

How often does an adult dog need shots?

Once the puppy series is done, your dog settles into a booster rhythm. Two rules apply here:

• Rabies - repeated at least every 12 months, because the law requires it.
• Other core vaccines - given at intervals your vet sets. Some products protect for longer and don't need yearly repeats, others (like leptospirosis) usually need an annual dose.

The simplest approach: stick to the dates in your dog's health record and ask your vet at every check-up what's due next.

Vaccines are one part of the bigger picture

Vaccines protect against viral and bacterial diseases, but they aren't the whole of preventive care. Internal and external parasites are a separate front you need to handle alongside them. For regular worm control, read our guide on deworming your dog, and for protection against ticks, see ticks on dogs.

It's worth pairing the vaccine conversation with tick prevention in particular, because some tick-borne illnesses can be every bit as serious as viral infections - more on that in tick-borne diseases in dogs.
