Dog and cat vaccinations are one of the topics that worry pet owners most: when to start, which vaccines are truly necessary, how often to give boosters, and how to avoid forgetting an important dose.
In this article you’ll find a practical guide to dog and cat vaccines, with a focus on:
- puppy and kitten vaccination schedules;
- boosters for adults and senior pets;
- the difference between vaccines required by law and those recommended by the veterinarian;
- how to organize reminders and vaccination records (also with the PawsPet app).
Important note: the information provided here is general. The vaccination plan should always be decided by the veterinarian, based on your pet’s health, age, and lifestyle.
Why dog and cat vaccinations are so important
Vaccinations are a prevention tool: they help the immune system of dogs and cats recognize and fight off certain diseases in advance, many of which are serious or potentially fatal.
Among the main benefits:
- they reduce the risk of severe infectious diseases (parvovirus, distemper, panleukopenia…);
- they limit the spread of viruses and bacteria even among unvaccinated animals;
- in some cases they are required by law (for example rabies vaccination in certain situations);
- they are often mandatory or strongly recommended for:
- travel abroad;
- boarding kennels, daycares, dog sitters/cat sitters;
- participation in events, competitions, and shows.
A good vaccination schedule for dogs and cats is therefore an essential part of their long-term health.
Dog vaccinations: basic schedule and main vaccines
Core dog vaccines
For dogs, people often talk about “core” vaccines (basic, recommended for almost all dogs) and “non-core” vaccines (recommended depending on the environment and lifestyle).
The most common core vaccines are:
- Distemper: a serious viral disease affecting the respiratory and intestinal systems, as well as the nervous system.
- Parvovirus: causes hemorrhagic gastroenteritis, often fatal in unvaccinated puppies.
- Canine infectious hepatitis (adenovirus): damages the liver and eyes.
- Leptospirosis: a bacterial disease that can also affect humans (zoonosis).
These vaccines are often given as combination multivalent vaccines (e.g. Distemper + Parvo + Hepatitis + Leptospirosis).
Non-core dog vaccines (optional but recommended in many cases)
Depending on lifestyle, the veterinarian may suggest other vaccines:
- Kennel cough (infectious tracheobronchitis): useful for dogs that go to boarding facilities, daycares, or crowded dog parks.
- Rabies: mandatory in some regions/situations and for:
- travel abroad;
- participation in international competitions;
- dogs living in border areas or high-risk zones.
- Other vaccines may be considered in specific areas (e.g. diseases transmitted by ticks in some geographic regions).
Dog vaccination schedule: puppy
The dog vaccination schedule can vary slightly from one veterinarian to another, but it usually follows this general timeline:
- 6–8 weeks:
- First multivalent vaccine (parvo + distemper ± others, at the veterinarian’s discretion).
- 9–12 weeks:
- Second dose of the multivalent vaccine (booster).
- 12–16 weeks:
- Third dose of the multivalent vaccine.
- Possible start or completion of the leptospirosis vaccine.
- Possible first rabies vaccination (depending on regulations/travel).
- Around 12 months (1 year):
- Booster for all vaccines given in the first year.
After the first year, the maintenance phase begins.
Booster shots for adult and senior dogs
The frequency of dog booster shots depends on the type of vaccine and the protocol chosen by the veterinarian:
- for some components (e.g. distemper, parvo, adenovirus) the booster may be every 3 years, if предусмотрed;
- for others (e.g. leptospirosis, some bacteria) an annual booster is often required;
- rabies follows local regulations: it is often annual or every three years, depending on the vaccine and current laws.
After the first annual booster, the veterinarian will define your personalized plan, specifying for each vaccine:
- when the last dose was given;
- when to give the next booster shot;
- whether it still makes sense to continue with all vaccines in old age or focus only on the essential ones.
Cat vaccinations: basic schedule and main vaccines
Core cat vaccines
Cats also have core vaccines, recommended for all cats, including indoor cats, because the risk of infection can come through objects, people, or occasional escapes outdoors.
The main core cat vaccines are:
- Feline panleukopenia (also known as “feline distemper”): a very serious viral disease, especially in kittens.
- Feline viral rhinotracheitis (feline herpesvirus): causes respiratory symptoms, conjunctivitis, sneezing, and fever.
- Feline calicivirus: affects the respiratory tract and oral cavity (ulcers, stomatitis), and sometimes the joints.
These three are often given as a trivalent vaccine.
Non-core cat vaccines
Among the most common additional vaccines:
- Feline leukemia (FeLV): particularly recommended for cats that go outdoors, live in groups, or have contact with unknown cats; a test is usually done first to confirm the cat is negative.
- Rabies: important for travel abroad, high-risk areas, or specific regulations.
- Other vaccines may be considered in very particular situations, always on veterinary advice.
Cat vaccination schedule: kitten
A typical cat vaccination schedule (indicative) includes:
- 8–9 weeks:
- First dose of the trivalent vaccine (panleukopenia + rhinotracheitis + calicivirus).
- Possible first FeLV dose if indicated.
- 12 weeks:
- Second dose of the trivalent vaccine (booster).
- Second FeLV dose (if planned).
- 12–16 weeks:
- Possible rabies vaccination (if needed for travel/regulatory reasons).
- At around 1 year of age:
- Booster for the trivalent vaccine and any optional vaccines given (FeLV, rabies).
As with dogs, after the first year cats move into the phase of regular boosters.
Booster shots for adult and senior cats
The frequency of cat booster shots can be:
- annual for some components;
- every two or three years for others, depending on the vaccine and protocol.
The veterinarian will consider:
- whether the cat lives exclusively indoors or also goes outside;
- whether it lives with other cats;
- any chronic conditions;
- age and immune status.
In senior cats or cats with chronic diseases, the vaccination plan may be adjusted by reducing vaccines that are not strictly necessary, but this assessment is always up to the veterinarian.
Required dog and cat vaccines: what the law says
In Italy, there is no single fixed, unchanging national list of required vaccines for dogs and cats, because some decisions are regional or linked to specific situations (travel, events, etc.).
Rabies: when it is required
Rabies vaccination is the most clearly regulated:
For dogs:
- it is often required:
- for export/travel abroad (e.g. trips within Europe and outside Europe);
- to take part in competitions, shows, or working trials in certain contexts;
- in some regions or areas considered at risk (check local regulations);
- the dog must:
- be microchipped;
- have the European pet passport for travel abroad;
- observe the minimum waiting period after vaccination before entering some countries.
For cats:
- rabies is required:
- for travel abroad;
- in some events or facilities;
- under certain local regulations.
Other vaccines may be required by private rules:
- boarding kennels for dogs/cats;
- daycares;
- professional dog sitters or cat sitters;
- shelters or colonies.
In these cases, it is not a general “legal requirement,” but rather a condition for accessing the service.
How long vaccinations last: protection and boosters
The duration of vaccine protection is not the same for every vaccine:
- some provide longer-lasting protection (even several years);
- others require frequent boosters, often annually.
A few points to keep in mind:
- A vaccine does not protect “forever”: you need to maintain antibody levels with the recommended boosters.
- A delay of a few days in a booster usually does not cancel everything, but very long delays may require restarting the vaccination series.
- In some situations (travel, boarding, competitions) checks are strict: if the booster has even slightly expired, the dog/cat may:
- not be allowed to travel;
- not be admitted to the facility.
That’s why it’s useful to have an always-up-to-date vaccination schedule and reliable reminders.
How not to forget dog and cat vaccine boosters
Between work, errands, and family life, it’s easy to forget the booster date. Here are some practical tools to help avoid that:
1. Paper planner or home calendar
- Right after each visit, write down the date of the next vaccine booster:
- for each animal (if you have more than one);
- specifying which vaccine (e.g. “Dog lepto – booster”, “Cat trivalent”).
- Use different highlighters or colored labels for dogs and cats.
2. Digital calendar (Google Calendar, etc.)
- Create a shared family calendar dedicated to your pets.
- Add “vaccine” events with:
- a reminder at least 1 month in advance (to book the visit);
- another reminder 1 week before;
- a note with the vet’s name and contact details.
3. Pet health management app (like PawsPet)
A dedicated app like PawsPet helps you:
- create a complete profile for your dog and cat;
- record:
- vaccines given;
- medications;
- parasite prevention treatments;
- veterinary visits;
- receive automatic reminder notifications for boosters (vaccines, parasite prevention, check-ups);
- always have the essential medical history on your smartphone, useful if:
- you change veterinarian;
- you travel and need to prove vaccination status;
- you leave your pet with sitters or boarding facilities.
Dog and cat vaccination costs: how to make sense of them
The costs of vaccines for dogs and cats can vary depending on:
- city or region;
- type of clinic (large hospital, small practice, independent vet);
- type of vaccine (single, dual, trivalent, multivalent; core or non-core);
- any pre-vaccination tests (FeLV/FIV testing in cats, blood tests in at-risk animals, etc.).
In general:
- the first year (puppy/kitten) is the most expensive, because:
- there are more visits;
- more doses are administered (primary series + close boosters).
- in the following years, the cost tends to stabilize around periodic boosters.
Practical tips for managing costs:
- ask your veterinarian for an annual estimate of vaccine and prevention expenses;
- consider health packages or prevention plans if your vet offers them;
- keep track of veterinary expenses (for example, with PawsPet you can log costs for vaccines, visits, and tests) so you have a clear view of your budget.
Remember: vaccination is a prevention expense that can save you from far higher costs in the event of serious illness.
What happens during a vaccination visit
Vaccination is not just “a shot”: it is part of a routine clinical check-up.
Usually the veterinarian will:
- perform a general exam:
- listen to the heart and lungs;
- check the eyes, ears, mouth, and skin;
- assess weight and nutritional condition;
- ask about:
- any recent symptoms (coughing, diarrhea, vomiting, lethargy);
- changes in diet;
- recent travel or contact with other animals;
- assess whether there are any temporary contraindications to vaccination:
- fever;
- ongoing acute illness;
- special medication treatments.
If everything is normal, they proceed with the vaccine administration, noting it:
- in the pet’s vaccination booklet;
- in the clinic’s records;
- in the passport, if it is a rabies shot.
This is also a great opportunity to:
- ask questions about diet, parasite prevention, and behavior;
- update the vaccination schedule;
- plan the next visit and routine check-ups.
Practical tips for managing vaccinations at their best
Before vaccination
- Observe your dog or cat in the days before:
- appetite;
- energy;
- stool and urine;
- coughing, sneezing, or eye/nasal discharge.
- If you notice anything unusual, tell the veterinarian before the shot.
- Bring with you:
- the health booklet;
- a list of any current medications;
- any questions you’ve written down.
After vaccination
It’s normal for mild reactions to appear in the 24–48 hours after vaccination, such as:
- mild tiredness;
- temporary reduced appetite;
- a small swelling or soreness at the injection site;
- a slight fever.
Contact the veterinarian immediately if you notice:
- repeated vomiting;
- severe diarrhea;
- breathing difficulties;
- widespread swelling, hives;
- marked or prolonged lethargy.
These are rare, but it’s good to know that in exceptional cases more significant reactions can occur and require prompt attention.
Practical checklist: keep dog and cat vaccination schedules under control
A short checklist so you don’t get lost among dog vaccination schedules and cat vaccination schedules:
- I’ve chosen a main veterinarian and booked the first puppy/kitten visit.
- I asked for a written vaccination plan with indicative dates for the next boosters.
- I recorded, for each animal:
- the date of each vaccine;
- the type of vaccine (e.g. “multivalent,” “trivalent,” “FeLV,” “rabies”);
- any past reactions.
- I entered all important dates in:
- the home calendar;
- the digital calendar / PawsPet app.
- I know which vaccines are required:
- for travel (passport, rabies, specific tests);
- for boarding, daycare, or competitions.
- I scheduled an annual check-up visit beyond the vaccines, for a general health check.

FAQ about dog and cat vaccinations
How often should dogs be vaccinated?
After the initial puppy series (usually between 6 and 16 weeks, with 2–3 doses), a booster at 1 year is given. After that, some vaccine components require an annual booster, while others may be repeated every 3 years, depending on the vaccine and protocol. The veterinarian decides the frequency of dog boosters based on health and lifestyle.
How often should cats be vaccinated?
Kittens are generally vaccinated between 8 and 12 weeks (2–3 doses), with a booster at around 1 year. For adult cats, boosters may be annual, every two years, or every three years depending on the vaccine (trivalent, FeLV, rabies) and lifestyle habits (indoor vs outdoor). Only the veterinarian can determine the correct cat vaccination schedule.
Which vaccines are required for dogs and cats in Italy?
In Italy, there are not many vaccines that are “required” for all animals by law. Rabies vaccination is required in some regions/situations and for travel abroad (with an EU pet passport and country-specific rules). Other vaccines may be required by boarding facilities, daycares, or events (e.g. kennel cough, multivalent vaccines), but in that case they are service requirements, not general legal obligations.
What happens if I miss a booster for my dog or cat?
If the delay is short, the veterinarian may decide to give the booster without restarting the series. If the delay is long, however, it may be necessary to repeat a new vaccination cycle (for example 2 close doses) to restore good protection. For vaccinations required by law or for travel (such as rabies), an expired booster may not be considered valid for regulatory purposes: it is therefore important to always check the deadlines and, if in doubt, ask the veterinarian.
