Isle of Dogs - Ending Explained

The central conspiracy of Isle of Dogs is that the canine flu outbreak was deliberately engineered by Mayor Kobayashi and his party. His anti-dog agenda is not a matter of public safety but the culmination of his cat-loving ancestors' long-held grudge against dogs. Professor Watanabe, who creates a cure for the flu, is assassinated with poisoned wasabi to suppress the truth.

A significant plot twist is the revelation of Chief's true identity. When Atari gives him a bath, his dirty fur is washed away to reveal a white and black-spotted coat, identical to Spots. This reveals they are from the same rare, expensive breed, foreshadowing their connection. The most crucial twist comes when the pack finally finds Spots. He is not a captive but the leader of a lost tribe of dogs who were the original test subjects at a secret lab on the island. Spots reveals that he is Chief's older brother, whom Chief had long thought was dead. Furthermore, Spots is now a father-to-be and relinquishes his duty as Atari's bodyguard to Chief, completing Chief's character arc from a lone stray to a devoted protector.

In the final confrontation, Tracy Walker and the student activists present evidence of Kobayashi's corruption. Moved by Atari's haiku, Kobayashi has a change of heart and rescinds the extermination order. His aide, Major Domo, attempts to proceed with the extermination anyway, but a student hacker foils the plan, causing the poison to backfire on the dog-catchers. In the ensuing chaos, Atari is critically injured and needs a kidney transplant. In a final act of redemption, Kobayashi donates his own kidney to save his nephew. Ultimately, Kobayashi and his conspirators are jailed, and Atari becomes the new mayor of Megasaki, reintegrating dogs into society.

The most significant alternative interpretation of Isle of Dogs revolves around the controversy of cultural appropriation versus cultural appreciation. While the mainstream reading sees a tale of loyalty and political allegory, a critical perspective views it as an example of Orientalism. In this interpretation, the film uses Japan as an exotic, aesthetic backdrop without deeply engaging with its culture or giving agency to its Japanese characters. The dogs, who speak English with American accents, are seen as the relatable protagonists, while the Japanese humans are rendered as "other," with their language often left untranslated.

Another point of contention is the role of Tracy Walker. She can be seen as a heroic activist fighting for justice. Alternatively, she is interpreted as a "white savior" figure, a trope where a white character rescues people of color from their own problems. This reading suggests that the film implies the Japanese pro-dog activists are incapable of saving the day without the leadership of a decisive American. However, some analyses counter this by pointing out that Tracy's direct efforts are ultimately thwarted by the Mayor, and the final victory is a more collaborative effort.

Finally, some have read the film through a Marxist lens, with the dogs representing a proletarian class, cast out by the capitalist, authoritarian Kobayashi regime. Their pack-like, democratic decision-making contrasts with Kobayashi's tyranny, and their eventual uprising represents a populist socialist victory.
