pursue her interest in painting animals by bringing live animals to the family's studio for studying. 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 Nicolas Poussin and Peter Paul Rubens, though she also copied the paintings of Paulus Potter, Frans Pourbus the Younger, Louis Léopold Robert, Salvatore Rosa and Karel Dujardin. She studied animal anatomy and osteology in the abattoirs of Paris and dissected animals at the École nationale vétérinaire d'Alfort, the National Veterinary Institute in Paris. There she prepared detailed studies that she later used as references for her paintings and sculptures. During this period, she befriended the father-and-son comparative anatomists and zoologists, Étienne Geoffroy Saint-Hilaire and Isidore Geoffroy Saint-Hilaire.

There is a reduced version in the National Gallery in London. This work led to international fame and recognition; that same year she traveled to Scotland and met Queen Victoria, who admired Bonheur's work. In Scotland, she completed sketches for later works including Highland Shepherd, completed in 1859, and A Scottish Raid, completed in 1860. These pieces depicted a way of life in the Scottish highlands that had disappeared a century earlier, and they had enormous appeal to Victorian sensibilities. Bonheur exhibited her work at the Palace of Fine Arts and The Woman's Building at the 1893 World's Columbian Exposition in Chicago, Illinois. In 1889 and 1890 she developed
