Brittany Ferries check in jobsworth refused to let us baord with out yellow lab....claimed her French passport was incorrect and ashe would be denied entry on arrival in France . We pointed out it had been used multiple times without issue. But like talking to a brick wall "computer says no". We ended up giving up on a club cabin booking and drove 5 hours to Dover where we crossed the next morning - without issue of course. We have taken dogs to France 30 or 40 times in the last few years and think we know more than these idiots as to what is and is not acceptable documentation. Not that the French ever even look at it.
