A sixteen-year-old boy grew up in a troubled home. His parents were divorced, his family broken, and he had no interest in studying. Still, for a time, he worked hard in hopes of building a good life. On his way to deliver food, he died in a traffic accident. When he woke up, he discovered he'd transmigrated into the little dog he'd hated most in his previous life: a Border Collie.
As a dog, Tutu the Border Collie used the intelligence of his sixteen-year-old human self and his dog's keen senses to gain all sorts of things he'd once longed for as a human but never had: affection, exceptional learning ability, travel, competitions, and the glory he shared with his owner. He even found love.
