Pierre Bonnard and His Dogs offers a fresh perspective on the painter’s work through the central place his dogs held within it. Present in his photographs, drawings, and paintings—from his Nabi beginnings to his final years in Le Cannet—they accompanied both his artistic journey and his private life. Drawing on rare sources, Stéphane Guégan shows how these companions shaped Bonnard’s vision: they animate his compositions, disrupt perspective, and bring movement, tenderness, and moral reflection. The book traces this relationship from the joyful decorative scenes of his early years to the later works marked by solitude shared with Marthe. As the fourth title in the Amigos Forever series, it sheds new light on one of the most sensitive painters of the twentieth century and reveals how, through his dogs, Bonnard reflected on creation, freedom, and the vital connection uniting all living beings.
