HI also if you come through serbia we were told this makes your pet pastport invalid and will have to get a new 1 as the animal is out of eu, better romaina, take a look at our route on here, most eu hotels take animals, and norfolk line dover to dunkirk only charge for taking the animal back not bring it out so its free your way as well,
hope this helps,
If you want to speek happy to help an were on sykpe
