Doraemon: Nobita no Wan Nyan Jikuuden

Nobita discovers a dog in danger of drowning and rescues it, hiding it in a wall-mounted kennel and naming it Ichi. He later takes in a cat named Zubu and several other stray animals. To manage the growing number of pets, Nobita and his friends send them 300 million years into the past using a time machine, equipping them with the Ray of Evolution to use a food-making device. They intend to return the next day but are thrown off course by a time-space anomaly, landing 1,000 years earlier than planned. To their shock, the animals have developed a sophisticated society. With the time machine damaged, they seek help to fix it while learning of an impending asteroid impact. Nobita must now find a way to reunite with Ichi and uncover the connection to a dog named Hachi who looks like Ichi.
