EU pet passport issue
Source: BUS Rheinland-PfalzFor dogs, cats and ferrets traveling privately within the EU, all that is required is an EU pet passport (also known as a "pet passport") issued by a family veterinarian with proof of identification of the animal by means of a microchip (in rare exceptions, a tattoo) and a valid rabies vaccination.
For travel to the member states Ireland, Malta, Finland and the United Kingdom, stricter requirements apply regarding antiparasitic treatment, in particular echinococcal treatment (tapeworms).
