The dreaded b-word (Brexit) means that there is currently some uncertainty on how EU Pet Travel will work after 29th March 2019.
Current advice from DEFRA is to start the process with us at least 4 months before the intended date of travel.
If you are travelling outside the EU, there are different requirements dependent on which country you are travelling to (or which state in the case of the USA). It is therefore important you familiarise yourself with the entry requirements for the location you are travelling to. This can normally be found on the embassy website of the country.
You may also wish to consider using a specialist pet travel company who can advise on the individual requirements for your trip.
