The dogs develop their own language, which creates conflict in the pack. Prince becomes a poet and his passion for language is a source of pleasure for him. Some dogs appreciate his use of poetry and wit, but other dogs find it strange and hate it. Majnoun learns to understand and speak English, which forges a bond between him and a human (Nira) as they have long conversations and learn about one another.
The immortal gods Apollo and Hermes are fascinated with mortals on Earth because of their relationship with death. Throughout the book, the reader learns how each dog dies and whether or not the dog died happy. The death plots include murder and euthanasia. The death of humans is also part of the narrative along with how the dogs respond.
The novel includes several poems composed by Prince. At the end, the author includes a "note on the text" where he describes the poetry genre used throughout the novel.
Love and friendship
Several dogs form friendships (Bella and Athena; Dougie and Benjy) that they experience differently because of their gift of intelligence. Majnoun asks Hermes about love and Prince loves language.
