Ichi

イチ

Ichi is a dog that was once owned by Nobita. It was his very first dog.
Ichi first appeared when Nobita was practicing baseball with Gian and Suneo. The ball fell into a river, and Ichi attempted to retrieve it but nearly lost his life because he could not swim, so he had to be rescued by Nobita.
Ichi lived with Nobita for a while until they were nearly discovered by Nobita's mother. They were forced to flee using the Anywhere Door to a mountain area, where they found more stray cats and dogs. Eventually, Nobita came up with a plan to take all of them back to the past so they could live in a world of freedom.
