Hi, welcome to COL. Our dog Danny, and my parent's Misty both have their passports. Although they got their passports in GB we have taken them to France and back (Misty has been lots of times). We've never had any problems. It seems to me that the difficult or complicated bit is getting all the medical stuff and paperwork done beforehand. After that the actual travelling is really simple. I think they still have to be treated for fleas, worms etc. between 24 and 48 hours of coming into GB. This is usually done by injection and does leave our babies a bit sore, but nothing too awful. Then they scan the microchip at the port (we've only ever travelled by ferry) and then off you go. This may have changed a bit, and I'm no expert, but I hope it's a help. You can always chat to your vet if s/he speaks English.
