Super Shiro

To the Nohara family, Shiro is simply their quiet white dog. In secret, however, he transforms into the superhero Super Shiro and receives missions to protect the world. His greatest recurring assignment is to locate the legendary Bobobobobone before it falls into the wrong paws.

The rival dog scientist Dekapoo wants the bone's extraordinary power for his own plans of world domination, forcing Shiro into a race that carries him far beyond the Nohara home. Guided by the alien Bibo, the usually unassuming pet relies on sharp instincts and unexpected bravery while making sure his family never realizes what he does when he disappears.
