Austria requires every dog keeper (Halter) to pay a Hundeabgabe, a municipal levy that dogs must be registered for from three months of age. According to Austria's official oesterreich.gv.at guidance, the rate, the rules and the deadlines are set differently 'in jedem Bundesland' — in each of the nine states — with the responsible office being the local Gemeindeamt, or the Magistrat in cities with statutory status; in Vienna, it's handled by MA 6.

The obligation is tied to the dog's place of residence, not to a visit. The official guidance frames it entirely around registering and deregistering a dog as its keeper moves between municipalities — it doesn't describe any process for a short-term visitor bringing a pet into Austria for a holiday, which is a strong signal that this levy is a resident's concern rather than something a travelling pet owner needs to arrange.

One practical note if your trip is actually a longer-term relocation rather than a holiday: Vienna stopped issuing physical dog tags (Hundemarken) in 2012 and now checks the electronic microchip instead, and all dogs in Austria have been required to be chipped since 2010 — which is one more reason the chip-number consistency covered in the Documents section matters, whether you're visiting for a week or moving in for good.
