Pet Travel & Brexit

If the UK leaves the EU with no deal and is treated as an unlisted country, pet passports issued in the UK would not be valid for travel to the EU.

To make sure your pet is able to travel from the UK to the EU after 29 March 2019 in any scenario, you should contact your vet at least 4 months before travelling to get the latest advice.
