To allow your pet to return to the UK with Stena Line, they must have a valid Pet Passport. This involves your pet being fitted with a microchip, vaccinated and blood-tested against rabies. This will take some time, so be sure to plan well ahead.
It is important that you check the EU regulations to the Pet Travel Scheme by visiting www.gov.uk/take-pet-abroad or by calling 0870 241 1710. Please note that if you travel abroad with your pet without meeting the regulations of the Pet Travel Scheme, your pet may be placed into quarantine on its return to the UK for up to 6 months.
