Shiro, a seemingly ordinary dog, lives with the Nohara family and leads a seemingly ordinary life. With his human family often involved in various adventures, Shiro is frequently left to his own devices, and it is during these times when he is alone that the secret life of this extraordinary dog is revealed. For Shiro is no regular hound - he is Super Shiro, a superhero dog tasked with protecting the Earth from nefarious evil-doers. Whenever he puts on his super hero badge, he transforms into an ultra-cool canine protector of justice (complete with a deep, ultra-cool superhero voice). His mission is to find and secure the "Bobobobobone," a legendary dog bone that, it is said, grants its owner the power to rule the world.

A spin-off of the popular Crayon Shin-chan franchise, the series focuses on the adventures of Shiro, a seemingly-normal family dog who, when the Earth is threatened, secretly transforms into a canine superhero to protect the planet from nefarious villains.
