This paper deals with the study of the Wolf picture books for preschoolers by the French author Oriana Lallemand and their impact on children's development. The paper confirms that these picture books not only entertain children, but also have significant pedagogical potential. In the first part of the paper, the importance of encouraging reading from an early age is highlighted, and the paper also touches on the problem of reading in the Republic of Croatia. The importance of the program and promoting reading to encourage a love of books in children is discussed. After that, the paper focuses on the role of the wolf in pedagogy and investigates the impact of the wolf picture book series on children's education. The Croatian and French curricula were compared in relation to this topic. The most important part of my work was dedicated to the series of picture books about the Wolf. Topics, lessons and the way of editing picture books were analyzed and divided according to the age of the children. Wolf picture books help develop children's emotional, social and cognitive skills. Through Vuk's stories, children have the opportunity to learn about different emotions and learn how to understand and express their feelings. The wolf as a character provides the children's audience with examples of situations they can identify with and gives them tools to face challenges. In addition to emotional development, Wolf picture books also encourage social skills in children. Through stories about the Wolf, children learn about the importance of empathy, cooperation and communication. By developing these skills, children acquire the ability to understand and respect others, which is essential for their social integration and successful functioning in the community. In addition, picture books about the Wolf provide an incentive for the development of cognitive skills in children. Through Vuk's adventures, children develop critical thinking, logical reasoning and problem-solving skills.
