Luxembourg makes exactly one vaccination compulsory: rabies, from the age of twelve weeks. Everything beyond that is a judgement the practice makes with you, and how often a booster is due depends on the vaccine and on the animal. The appointment itself is mostly an examination; the injection is the shortest part of it.
What a vaccination does, and why the effect fades
A vaccination gives the immune system a safe preview of something the animal might meet later. The body builds a memory of it, and if the real encounter comes, it reacts faster and more precisely. That protection is real, but it is not a guarantee, and it does not last equally long in every animal. Vaccination shifts the odds in your animal’s favour; it does not switch the risk off.
That is exactly why boosters exist. Immune memory fades over time, at a pace that depends on the animal, its age and health, and the type of vaccine. A booster tops it up before it has drifted too far.
Two things surprise many owners. Young animals usually need several appointments in their first months, because the protection passed on by the mother wears off gradually and can also blunt a very early vaccination; the first course is therefore built over several visits. And not everything runs on the same clock: different vaccinations hold for different lengths of time, so an up-to-date plan rarely means “everything, every year”. Your practice keeps track of what is due when. If a booster is overdue, that is a reason to talk, not to feel guilty. Bring the record and ask how to pick the schedule back up.
What the law requires in Luxembourg
For dogs, one vaccination is not a matter of preference: rabies vaccination is compulsory in Luxembourg from twelve weeks of age. It belongs to a small set of duties that arrive together in the first months:
- Microchipping by a vet within four months of birth.
- Registration with your commune, also within four months.
- Civil-liability insurance from an insurer licensed in Luxembourg; proof is required when you register.
- The EU pet passport, issued by your vet, recording the chip number and the rabies vaccination.
In the Greater Region that passport is an everyday document, not a holiday one. A weekend in Germany, Belgium or France is ordinary life here.
Some dogs bring extra formalities. The law of 9 May 2008 lists the Staffordshire bull terrier, Mastiff, American Staffordshire terrier and Tosa as potentially dangerous, along with morphologically comparable dogs without a recognised pedigree. Extra duties apply, including the “Hondsführerschäin”. If you are unsure whether any of this concerns your dog, check with your commune.
Cats have rules of their own: the law of 27 June 2018 requires them to be identified and registered, and cats with outdoor access must be neutered, with farm cats excepted. Which vaccinations suit a particular cat, on the other hand, is not a legal question but a veterinary judgement.
The appointment: more examination than injection
The injection itself takes seconds. The larger part of the appointment is the examination, because an animal that is unwell is not vaccinated. Your practice asks about recent days, appetite, energy, drinking and digestion, weighs the animal, takes its temperature and checks eyes, ears, mouth, skin, lymph nodes, heart and lungs. Say so if your animal has seemed off recently or reacted to an earlier vaccination; postponing by a week or two is a sensible decision.
There is also a conversation about how the animal lives, and it is not small talk. Beyond the legal duty, vaccination is a weighing of risk, not a catalogue: indoors or roaming, dog park, boarding or shows, woodland and standing water, trips across the border, age, pregnancy, chronic illness, and how earlier vaccinations were tolerated. Two dogs of the same age and breed can sensibly end up with different plans. Describing honestly a cat that “only goes on the balcony, but the balcony is on the ground floor” changes the recommendation, as does the plan to board the dog for two weeks in August: those stays often come with requirements of their own.
Afterwards, a quiet day suits most animals. Mild tiredness, a smaller appetite or a tender spot at the injection site can happen and usually settles within a day or two. Difficulty breathing, a swollen face, hives, repeated vomiting, collapse or sudden weakness are a different matter: do not wait for the next appointment, contact a practice or the out-of-hours service immediately. In Luxembourg the small-animal out-of-hours service runs from 08:00 to 08:00 the following morning; the on-call lists are published by the Collège Vétérinaire, by the LAK under “GARDE” and by the AMVL. The general emergency number is 112.
Passport, chip number and your questions
- The pet passport or vaccination record, plus the chip number if you keep it separately.
- The date of the last vaccination.
- A secure carrier for cats, the lead for dogs.
- Your questions, written down. They tend to vanish in the consulting room.
Keep the passport with your other documents and take it along when you cross the border. Boarding kennels and any practice seeing your animal for the first time will ask for it; what your commune wants to see when you register is best checked with the commune itself.
Frequently asked questions
Is rabies vaccination compulsory for my dog in Luxembourg?
Yes, it is compulsory from twelve weeks of age. Alongside it, the dog must be microchipped by a vet within four months of birth, registered with your commune within four months, and covered by mandatory civil-liability insurance from an insurer licensed in Luxembourg, with proof required at registration. Your vet issues the EU pet passport recording the chip number and the rabies vaccination.
Why does my animal need boosters at all?
Because immune memory fades over time, at a pace that differs by vaccine and by animal. A booster tops it up before it has drifted too far. Not everything is due every year, and your practice keeps track of what is due when. If something is overdue, bring the record and ask how to pick the schedule back up.
My animal seems tired after the vaccination. Is that normal?
Mild tiredness, a smaller appetite or a tender spot at the injection site can happen and usually settle within a day or two. If there is difficulty breathing, a swollen face, repeated vomiting, collapse or sudden weakness, contact a practice or the out-of-hours service immediately. That service runs from 08:00 to 08:00 the following morning, and 112 is the general emergency number.
Do the same rules apply to cats?
The animal protection law of 27 June 2018 requires cats to be electronically identified and registered, and cats with outdoor access to be neutered, with farm cats excepted. Which vaccinations make sense depends on how the cat lives and is a veterinary judgement. For registration details, check with your commune.
Who can I reach at night or at the weekend?
The on-call practices run a 24-hour service that starts at 08:00 and ends at 08:00 the next morning. To reach the vet on duty you can call 112 or Post Infotel on 26 77 12 34, and the on-call list is published by the Collège Vétérinaire and on amvl.lu under GARDES. Our own emergency page lists the ones on duty right now with their numbers. Call before you set off: the vet on duty may not be at the practice and has to get there too.
