Rabies vaccination
Before your pet can travel, an authorised vet must vaccinate it against rabies. For the vaccination to be valid, your pet must be at least 12 weeks old and must have been microchipped before the vaccination is given. Your pet can travel 21 days after the completion of the vaccination protocol. You should make sure that any further vaccinations are given before the validity period of the previous one has expired.
In addition to the standard requirements (microchip, anti-rabies vaccination, anti-Echinococcus treatment where necessary, EU health certificate), your pet must have a rabies antibody test 30 days after their rabies vaccination and not less than 3 months before travelling to the EU. An authorised vet must take the blood sample for testing by an EU approved blood-testing laboratory.
The results of the rabies anti-body test must be attached to your pets EU health certificate.
Entering the EU with your pet
You can only enter the EU with your pet through a travellers point of entry in the EU country of destination, your pets documents and identity will be checked by the competent authorities. If your pet fails these compliance checks, it may be returned to the country of departure, be placed in quarantine until such time as it is complies with EU health rules or if neither of these options are possible, the animal may be euthanised.
