When the Official Veterinarian "OV" is completing your pet’s official travel documents (Animal Health Certificate or EU Pet Passport), make sure the date of implantation or date of reading of the microchip is the same date, or before, the date of the rabies vaccination
The certificate reference number must be written on each page of your pet’s Animal Health Certificate
Each page must be stamped with the official stamp of the OV/LVI (Local Veterinary Inspector) for British vets on your pet’s Animal Health Certificate
All relevant Section of an EU Pet Passport should be correctly filled and stamped where needed by your EU Official Veterinarian ("EU Vet").
For the Rabies Section of the EU Pet Passport make sure that vaccine name and manufacturer, date of vaccination, "valid from" and "valid until" dates, and EU Vet details or stamp and signature of your EU Vet are filled in dedicated boxes.
A GB/non-EU vet cannot complete the Rabies section of an EU issued pet passport.
If an EU vet inserts the non-EU/GB vet’s details on the Rabies section of an EU issued pet passport, such that it appears to have been completed by a GB/non-EU Vet it will invalidate the document. Travel will not be permitted.
The EU Vet must insert their own details or stamp and signature in the dedicated boxes on the EU pet passport.
If a Rabies vaccination in an EU issued pet passport has expired whilst the pet has been in GB, an Animal Health Certificate must be issued for travel. You will then need to attend an EU Vet to update your EU pet passport.
