A week out, gather the physical paperwork together: the EU pet passport or health certificate, and any state-specific registration details relevant to your dog's breed. Keep these somewhere accessible, not buried in checked luggage.

Pick up basic tick-prevention treatment now if you haven't already — available over the counter at any Austrian Apotheke, covered in the Shopping section — especially given Austria's own description of itself as one of Central Europe's most heavily affected FSME regions.

If any part of your trip involves Vienna and your dog is on the Wiener Hundeführscheinverordnung's breed list, confirm you have a correctly fitted muzzle ready to go, since the official rule applies even to a brief visit and must be fitted before you even enter a U-Bahn station, not just before boarding.
