Known in Japan as Jagainu-kun, Dogtato is the heartwarming tale of a dog that`s really a potato...or a potato that`s really a dog. Or something. (Jagaimo = potato, inu = dog, thus the name Jagainu/Dogtato.) Dogtato`s world is full of his lovable half-veggie, half-animal friends who are always getting into wacky hijinks and misadventures.
