Orthrus and his master, Eurytion, were charged with guarding Geryon's herd of red cattle in the "sunset" land of Erytheia ("red one"), one of the islands of the Hesperides in the far west of the Mediterranean. Heracles eventually slew Orthrus, Eurytion, and Geryon, before taking the red cattle to complete his tenth labor.

In one story, Orthos was captured and tamed by Oedipus.
