By three weeks out, the EU pet passport (or health certificate, if you're not an EU resident) should be finalised, with the microchip number, vaccination date and all other details checked for accuracy. A mismatch here is one of the most common, avoidable snags at this stage.
If you're driving in, this is the time to sort out Austria's motorway vignette, covered in the Transport section, rather than leaving it for the border itself. If your route passes through more than one Austrian state with a listed breed, double-check each relevant state's Listenhunde rule now, since they genuinely differ.
Confirm the specifics with wherever you're staying: pet fees, any size or breed restriction, and whether a lead is required within the property. If any part of the trip includes Hohe Tauern or another national park, note the park's own leash and access rules, covered in the Activities section, so route planning accounts for them.
