Premise: 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.
Hypothesis: The pet passport and the small purple folder that vets give out with vaccination history are two completely different things.
