evidence: Whilst the Department for Environment, Food and Rural Affairs (Defra) has confirmed there will be no checks or changes to the requirements for pets travelling from Northern Ireland to Great Britain, any person travelling from Northern Ireland to Great Britain with a pet and then returning to Northern Ireland, will be required to adhere to the EU requirements for travelling into the EU/Northern Ireland from a Part II listed country. However, Northern Ireland travellers will be able to obtain a valid EU pet passport in Northern Ireland to use as an alternative to an Animal Health Certificate. [...] From 1 January 2021 UK pet passports issued in both Northern Ireland and Great Britain up to 31 December 2020, are no longer valid for travel to the EU (including Northern Ireland). Interim measures have been put in place. If you are intending to travel you should contact your vet who will arrange to update your pet passport appropriately to allow travel. A new style UK (NI) branded EU Pet Passport will be distributed to every authorised Private Veterinary Practitioner in due course.
