A talking dog is a beautiful story that you should have dreamt of as a child. But if you have forgotten about it, this is a reminder of that fable story. This is the story of a dog that talks, but ordinary people cannot hear his voice. 
The main character, Mametaro, is an adventurous crossbreed dog. He loves his owner, Iku-chan and his girlfriend Hanako-chan very much. However, he just cannot stand Iku-chan's friend, Akiyoshi. 
During this story, which will be told from Mametaro's point of view, the warm days of spring are finally here. The school and the riverbank, which is actually just an ordinary neighborhood for people, seems like a mysterious world that extends infinitely to little Mametaro and his friends.
