Dog vaccination: mandatory vaccinations, intervals & current
Vaccination in dogs: essential vaccinations, intervals & current
What is vaccination in dogs?
Vaccination is the targeted stimulation of the immune system using an attenuated, killed, or recombinant antigen in order to build a protective immune response against a pathogen — without having to go through the full disease. In dogs, vaccinations are the most important preventive medical tool against life-threatening infectious diseases.
Vaccination recommendations are coordinated internationally by the WSAVA (World Small Animal Veterinary Association) and adapted nationally for Germany by the Standing Committee on Vaccination in Veterinary Medicine (StIKo Vet). The central principle: vaccinate as much as necessary, as little as possible.
Background + scientific classification
Day et al. (2016, Journal of Small Animal Practice, PubMed 27345492) published the current WSAVA vaccination guidelines: core vaccines (essential vaccinations for every dog) are canine distemper virus (distemper), canine adenovirus (hepatitis), canine parvovirus type 2, and rabies. Non-core vaccines (situation-dependent) include Bordetella/canine parainfluenza virus (kennel cough), leptospirosis, and Lyme disease. The guidelines emphasize: annual booster vaccinations for core vaccines are not generally scientifically justified — titer tests or 3-year intervals are valid alternatives.
Schultz et al. (2010, Journal of Comparative Pathology, PubMed 20580023) investigated long-term protection after vaccination in dogs and cats: immunity from core vaccines lasts significantly longer than one year in many dogs — studies demonstrate protection for 5–7 years after complete primary immunization. Maternal antibodies interfere with puppy vaccination: the final puppy vaccination should not be given before 16 weeks of age in order to minimize vaccine failure caused by maternal antibodies.
Mitchell et al. (2012, Veterinary Record, PubMed 22337846) analyzed the duration of serological response after polyvalent vaccination: The majority of dogs with a complete primary puppy immunization maintained protective antibody titers for more than three years. However, individual variation is considerable — titer tests (serum antibody titers for distemper/parvo) can help avoid unnecessary booster vaccinations.
Vitomalia position
Vaccination is not a bureaucratic obligation — it is the most scientifically sound protection against diseases that can be fatal without vaccination. At the same time: annual revaccination with all core vaccines is not evidence-based. Modern guidelines allow individual vaccination intervals — a conversation with your veterinarian and, if appropriate, a titer test are more useful than a rigid yearly schedule.
When does vaccination become relevant for dogs?
- Puppy vaccination: primary immunization from 8 weeks of age, last vaccination not before 16 weeks of age
- Adult dog: booster for core vaccines after 1 year, then every 3 years or based on a titer test
- Travel to endemic areas: leptospirosis, rabies, ehrlichiosis
- Before boarding, Dog Training Academy, dog show: kennel cough vaccination recommended
- If vaccination status is unknown (animal from abroad): repeat the complete primary immunization
Practical use
Vaccination schedule — overview for Germany:
| Vaccine | Type | Booster interval | Note |
|---|---|---|---|
| Distemper (CDV) | Core | Every 3 years | After puppy primary immunization |
| Parvovirus (CPV-2) | Core | Every 3 years | Last puppy vaccination: 16th week of life |
| Adenovirus/hepatitis (CAV) | Core | Every 3 years | Often combined with CDV/CPV |
| Rabies | Core (required for travel) | 1–3 years | Required for international travel |
| Leptospirosis | Non-core | Annually | Regionally relevant (water areas) |
| Bordetella/CPIV | Non-core | Annually | Before boarding/social contact |
Titer test as an alternative: - Blood test measures antibody levels against distemper and parvo - Sufficient titer = vaccination not necessary - Alternative to routine vaccination recognized by WSAVA and StIKo Vet
Common mistakes & myths
- “My dog stayed indoors — vaccination isn’t necessary.” Parvovirus can survive for months in the environment; transmission via shoes, clothing, and contact is possible. No housing situation provides complete isolation.
- “Vaccinating every year is the safest option.” Not scientifically proven for core vaccines. Overvaccination has rare but documented risks (vaccination reactions, vaccine-associated sarcomas in cats — less common in dogs). WSAVA guideline: 3-year interval for core vaccines.
- “Puppy vaccination is enough — no boosters are needed.” Immune protection decreases over time. Primary immunization without a booster after 12–16 months is incomplete.
Scientific status 2026
The trend toward evidence-based, individualized vaccination medicine for dogs is established worldwide. StIKo Vet updates its recommendations regularly — currently, 3-year intervals for core vaccines and titer tests are explicitly recognized as valid alternatives. New vaccines against canine influenza virus and Ehrlichia are in development and are relevant for dogs traveling to Southern Europe.
Frequently asked questions
Which vaccinations does my dog absolutely need?
Core vaccines for every dog in Germany: distemper, parvovirus, adenovirus/hepatitis. Rabies is required for international travel. Leptospirosis and kennel cough depend on lifestyle and region. Discuss a specific recommendation individually with your veterinarian.
How often do I need to have my dog vaccinated?
Puppy primary vaccination: several partial vaccinations, with the final vaccination no earlier than 16 weeks of age. First booster after 12–16 months. After that, core vaccines every 3 years or after a titer test. Non-core vaccines (leptospirosis, kennel cough) annually.
What is a titer test and when does it make sense?
A titer test measures antibodies in the blood against distemper and parvovirus. If it shows sufficient protection, a booster vaccination is not necessary. It can be useful for dogs with a history of vaccine reactions, in cases of insecurity about actual vaccination protection, or as an alternative to routine annual vaccinations.
