On an ordinary day, Nobita came across a clever and lovely puppy. The dog was so attached to him that Nobita had no choice but to ask Doraa to dream of adoption. At the same time, there are more and more abandoned cats and dogs around, and the friends are so worried that they can't even find a place for the animals to settle down in the back mountain. In desperation, Nobita brought small animals to prehistoric times when even dinosaurs had not yet been born, and used evolutionary degradation guns to promote the evolution of animals. The next day, the friends went to see the small animals in accordance with the agreement, but they were hit by turbulence in the time and space tunnel. We have come to an era thousands of years earlier than the day before. At this time, the country of cats and dogs has been unprecedentedly prosperous, and they have met a kind of friends such as Hachi here. It was soon learned that the earth would be hit by meteorites, and a plot was brewing within the country of cats and dogs. This is where a new adventure begins. This film commemorates the 25th anniversary of Doraemon Theatre version.
