Cú Sídhe: Irish Fairy Dog in Celtic Folklore

Cú Sídhe is a feared figure in Irish and wider Gaelic folklore, a supernatural hound of the Aos Sí that appears as both guardian and omen. Described as an uncanny fairy dog tied to the otherworld, its stories reveal how sound, landscape, and death were woven into Celtic belief—and why the creature still captivates readers today.
