I have done the same and it is fine if Pup is under 3 months old, but in countries that required Rabies vaccination pups over 3 months have to be vaccinated.
I thought France were one of the sticklers? and this part refers: "2. Valid vaccination against rabies (first vaccinations and boosters" as they don't allow unvaccinated pups under 3 months like other EU countries "Since 28 May 2004, pets who are under three months old and not vaccinated against rabies are not allowed to enter into France"
I wonder how the Dutch people who took their pup in Sept 2005 managed as they went by Eurotunnnel. Maybe transit arrangements are different as she had her Pet Passport but not her Rabies shots being only 8 1/2 weeks old.
