| In short : Vaccination remains the most effective way to protect your dog from seriously disabling, even fatal, viral or bacterial diseases. Here’s what to remember for the year 2026: – No vaccine is strictly mandatory by law for a “citizen” dog in France: However, the rabies vaccine is legally required to cross borders, for category dogs (1 and 2), and often required in campsites or pensions. – Essential vaccines (highly recommended): They protect against square disease, parvovirus and Rubarth’s hepatitis. They are essential for all dogs, without exception. – Optional but crucial vaccines depending on lifestyle: Leptospirosis (country dogs or hunters), kennel cough (communities, canine clubs) and leishmaniasis (Mediterranean area) depend on your pet’s profile. – The vaccination protocol: The primary vaccination occurs from the age of 8 weeks (in 2 or 3 injections), followed by an annual booster or every 3 years depending on the valences of vaccines used. |
Taking care of your four-legged friend involves offering him a quality diet, exercise, but also rigorous medical follow-up. In 2026, preventive veterinary medicine insists more than ever on the importance of an up-to-date vaccination schedule.
Faced with the regular reappearance of certain epidemics (such as parvovirus) or the resurgence of diseases linked to environmental changes, taking stock of vaccines is essential. So what are the mandatory vaccines, those recommended, and how often should they be administered? Follow the guide.
Mandatory VS Recommended: What does the law say?
There is often confusion among dog owners between what is Medically essential and what is legally mandatory.
In France, if you have a classic companion dog and you are not traveling, the law does not impose any vaccination on you. However, several specific situations make certain vaccines legally compulsory.
The special case of the rabies vaccine (R)
The rabies vaccine is the only one to be strictly regulated by legislation. It becomes mandatory if:
- You are traveling abroad with your dog (the European passport is then required).
- You have a guard or defense dog (category 2) or an attack dog (category 1).
- You go to certain specific public places (canine boards, campsites, competitions) which explicitly so in their rules of procedure.
“Essential” vaccines: the basis for all dogs
The global veterinary community classifies vaccines into two categories: essentials and optional. Essential vaccines should be given at All dogs, regardless of their lifestyle (apartment or open air), because the targeted viruses are extremely resistant in the environment and often deadly.
1. Parvovirosis (P)
This is the fear of breeding and puppy owners. This ultra-resistant virus causes severe hemorrhagic gastroenteritis. Without rapid medical care, the mortality rate in puppies is extremely high.
2. Square disease (C)
This highly contagious viral disease attacks the dog’s respiratory, digestive and nervous systems. Even if a dog survives, it generally has heavy neurological sequelae for life.
3. Rubarth’s Hepatitis (H)
Rare today thanks to vaccination, this viral condition targets the liver, kidneys and eyes. It can cause sudden death in young animals.
“Optional” vaccines: to be adapted according to the lifestyle
These vaccines are no less important, but they are aimed at dogs exposed to specific risks related to their geographical environment or their activities.
1. Leptospirosis (L)
Nicknamed the “disease of the rat”, this bacterium is transmitted by the urine of rodents, often present in stagnant waters (puddles, ponds, rivers). it causes dazzling kidney and hepatic failure and turns out to be a zoonosis (transmissible to humans). It is highly recommended for country dogs, hunting, or swimming enthusiasts.
2.Kennel cough (pi/BB)
due to a combination of viruses (parainfluenza) and bacteria (Bordetella Bronchiseptica), it leads to very contagious tracheobronchitis. It is essential if your dog frequents congeners (canine clubs, dog parks, boarding houses, exhibitions).
3. Leishmaniasis and piroplasmosis
- Piroplasmosis: Transmitted by ticks, it destroys red blood cells.
- Leishmaniasis: Transmitted by the sandfly (a small mosquito), it mainly prevails in the Mediterranean basin. This vaccine is strongly recommended if you live or travel to the south.
Summary table: Dog vaccines in 2026
| Target disease | Usual initial | Legal / medical status | Major risks | Reminder frequency |
| parvovirus | p | Essential | Fatal gastroenteritis | Every 3 years (after call back at 1 year) |
| square disease | C | Essential | Nerve and respiratory damage | Every 3 years (after call back at 1 year) |
| Rubarth’s hepatitis | h | Essential | Severe hepatic impairment | Every 3 years (after call back at 1 year) |
| Rage | r | Mandatory (according to context) | Fatal disease communicable to humans | Every 1 to 3 years (depending on the brand) |
| leptospirosis | l | Recommended (according to profile) | Renal impairment (zoonosis) | Every year (sometimes every 6 months) |
| kennel cough | PI / BB | Recommended (Collectivity) | Contagious respiratory infection | Every year |
The vaccination schedule of the puppy and the adult dog
For a vaccine to be fully effective, the protocol must be scrupulously respected.
The primary vaccination of the puppy
When the puppy is born, it is protected by its mother’s antibodies (colostrum). This immunity falls between the 6th and 12th week. This is when the vaccination relay must be taken:
- 8 weeks (2 months): First injection (usually CHPL: square, hepatitis, parvovirus, leptospirosis).
- 12 weeks (3 months): Second injection (CHPL + rage if necessary).
- 16 weeks (4 months): Third injection (highly recommended in 2026 to counter late maternal immunity drops on parvovirus).
Reminders in adults
The first complete reminder comes 1 year after primary vaccination. Then, the Sallege rhythm: leptospirosis and kennel cough require a reminder annual, while CH (square, hepatitis, parvovirus) and rabies often only require a reminder every 3 years.
FAQ: Your Frequently Asked Questions
My dog lives in an apartment, should he be vaccinated?
Yes, absolutely. Ultra-resistant viruses like that of parvovirus can be carried under your own shoe soles or on your clothes after a simple walk outside. The apartment does not protect your dog from invisible diseases.
What are the possible side effects of a vaccine?
In the majority of cases, the dog simply has a slight fatigue or a small loss of appetite for 24 to 48 hours. A small painless swelling may appear at the injection site and disappears in a few weeks. Serious allergic reactions (shock) are extremely rare.
Can an old dog be vaccinated?
Yes, and it is even recommended. With age, the dog’s immune system is aging (immunosenescence) and becomes less effective in fighting infections. Continue vaccination (especially against leptospirosis) protects your Senior dog when he is most vulnerable.
