Hello. I'm just about to drive over to Belfort with my dog: my partner has a job out there for a year. I think we'll be going through the tunnel so Bruce (the dog) and I can stay together, but I have done some research into ferry crossings. I found this on a website, covering all ferry crossings leaving Britain, I think. P&O Dover, P&O Portsmouth & Hoverspeed: Pets must remain in the vehicle during the crossings - Owners do not have access to their pets during the crossing. Hoverspeed also insist that animals must be secured inside the vehicle (eg. in a cat box, or in the boot behind a dog guard). Brittany Ferries: Pets must remain in the vehicle during the crossings - Owners may see their pets during the crossing, but must be accompanied by a member of staff. Stena Line You can choose for your pet to travel in your car or in a kennel aboard the ship. Guide dogs are allowed to travel on the passenger decks with their owners. P&O North Sea Ferries Hull Pets are accommodated in the on board kennels - Owners may see their pets during the crossing. I hope this is useful to you. Good luck with the journeys! Pip
