The pet passport is a pink A4 sheet which contains the microchip number and certification that the dog has a rabies vaccination, and needs to be signed by a veterinary surgeon who has LVI status. The passport is not to be confused with the much smaller purple folder routinely issued by vets which records the complete vaccination history of the pet.
The pink A4 sheet must always be signed by a vet who has LVI status.
According to the context, the A4 sheet must be signed by a veterinarian surgeon with LVI status.
