That district was dissolved in 1938, so Dotternhausen was again reassigned, this time to the newly created Landkreis Balingen [de].

[3] The municipality (Gemeinde) of Dotternhausen covers 10 square kilometers (3.9 sq mi) of the Zollernalb district of Baden-Württemberg, one of the 16 States of the Federal Republic of Germany.

The primary watercourses in the municipal area are the Schlichem, which forms its southern border, and the Katzenbach, which flows into the Eyach near Balingen.

[3] Dotternhausen's coat of arms displays a stag in yellow, posed and facing left, over a field of blue.

This pattern was used by the Lords of Dotternhausen Castle [de], but the blue-yellow tincture was an addition by the municipal government.
