Most films released in German-speaking areas in Europe are dubbed in Germany with the same standard German pronunciation. This film, however, was also released in a special version that was re-dubbed for Austria. Each of the animals speaks in a very specific regional Austrian accent: Ferdinand the Duck sounds like a Tyrolean, Duchess the cat has a Vorarlberg accent and so on. The mice sing Styrian folk songs. This Austrian version was included on the DVD, however not on the Blu-ray.
