Isle of Dogs (2018) Timeline Explained – Every Event in Order

Mayor Kobayashi exiles all dogs citing the dog-flu virus as justification, but his true motivation stems from the Kobayashi family's thousand-year history of suppressing dogs. Their ancestor was a cat enthusiast who sought to eliminate canines from Japan. The mayor's nephew Atari's close bond with his dog Spots particularly angers him, as it represents everything he opposes. The exile is actually a cover for his ultimate plan: extermination.

Foreshadowing: Early scenes establish the mayor's visible contempt for Atari's relationship with Spots, hinting at deeper family animosity toward dogs.
