The document discusses and analyzes the posters for three dog-themed films: Marley and Me, The Shaggy Dog, and Beethoven. For the Marley and Me poster, the simplicity draws attention to the dog and conveys the time period. The Shaggy Dog poster features an extreme close-up of the dog to show he is the main character. The Beethoven poster depicts the dog balancing the family on his head to make him seem superior in a funny way.
