In almost all of his paintings, Dupre's peasants loom large - whether milkmaids, girls feeding chickens or geese, harvesters, or women guarding flocks of sheep. While maintaining the Barbizon heritage initiated by Jean Francois Millet, Dupre achieved in his figures a presence usually associated only with Leon L'Hermitte or Jules Breton. Dupre proved a most popular painter in other countries, and many of his oil paintings entered public and private collections in the United States.
