The dahu is a legendary creature well known in France, Switzerland and the north of Italy (particularly in French-speaking Aosta Valley).

French, Italian and Swiss pranksters often describe the dahu as a mountain goat-like animal with legs of different sides having differing lengths to fit the mountain's side.

Regional variations on its name include dahut or dairi in Jura, darou in Vosges, daru in Picardy, darhut in Burgundy, daù in Val Camonica; also called a tamarou in Aubrac and Aveyron, and tamarro in Catalonia and Andorra. The dahu cub is called a dahuot. (source)
