Following the traditional art school curriculum of the period, Bonheur began her training by copying images from drawing books and by sketching plaster models. As her training progressed, she made studies of domesticated animals, including horses, sheep, cows, goats, rabbits and other animals in the pastures around the perimeter of Paris, the open fields of Villiers near Levallois-Perret, and the still-wild Bois de Boulogne. At fourteen, she began to copy paintings at the Louvre. Among her favorite painters were Nicholas Poussin and Peter Paul Rubens, but she also copied the paintings of Paulus Potter, Frans Pourbus the Younger, Louis Léopold Robert, Salvatore Rosa and Karel Dujardin.
