• hundesteuer_by_state

  Average German dog tax (Hundesteuer, first dog per year) per Bundesland (federal state), aggregated over the covered largest cities — the data behind the Deutschlandkarte. Answers 'which German state has the highest/lowest dog tax'. Note: a mean over cities, not an official state rate (the tax is municipal).

  shallow
• hundesteuer_changes

  List German cities that changed their Hundesteuer (dog tax) rate in a given year — the fresh-news angle for the annual city comparison. Only 2026 is curated, and it is the default: 14 of the covered cities changed their rate, led by Köln (174 EUR), Lübeck (156 EUR), Lünen (156 EUR). Also returns outlook_2027: 5 cities that have announced or resolved an increase for 2027 but are NOT yet charging it — announced and in force are kept apart deliberately. Every entry checked individually against the municipal statute.
