Eurotunnel Le Shuttle is widely considered the easiest way to bring a pet into Great Britain by land, mainly because the pet never has to leave the car. Dogs, cats and ferrets travelling under the pet travel scheme need the same documents covered elsewhere in this guide — microchip, AHC, rabies vaccination, and for dogs, the tapeworm treatment given 24–120 hours before the Calais-to-Folkestone crossing specifically.
Add your pet when you book your own Le Shuttle ticket, and arrive at the terminal with extra time: all pets must check in at the dedicated Pet Reception centre, which operates 24 hours a day at both the Folkestone and Calais terminals, with an exercise area and a pet lounge. Checking in takes only a few minutes once you're there, but Eurotunnel recommends building in at least 90 minutes before your booked departure to allow for it.
The crossing itself takes roughly 35 minutes, and your pet stays with you in the vehicle throughout — no separate hold, no being handed off to anyone. It's a genuinely low-stress option compared with flying, which is a large part of why it's become the default route for many pet owners crossing between the EU and Great Britain.
