Andorra maintains excellent relations with its European neighbours. Although it does not belong to the Schengen Area, it has free movement agreements with Spain and France. Andorra does not require an Andorran visa for entry. However, if you are coming from a country that requires a Schengen visa to enter Spain or France, make sure that it is a multiple-entry and exit visa if you wish to travel to Andorra without any problems.
If you are travelling from a non-EU country, you will also need to have a good health certificate and pass a customs control upon entering the European Union. If the number of animals travelling is greater than 5, in addition to requirements 1, 2 and 3, an official health certificate known as TRACES is required. If your pet is a wild or part-wild animal indigenous to the local fauna or otherwise, you will need to request authorisation to import it via a generic application to the Permit Service (Servei de Tràmits) of the Andorran Government, directed to the Department of Natural Heritage (Departament de Patrimoni Natural). Depending on the species of animal, you will need to attach certain documentation outlined in the Regulations covering the conditions of carriage, import and export of wild animals.
