Dogsbody by Diana Wynne Jones

A celestial being condemned to live on Earth in a dog’s body must adapt to human life when he is taken in by a lonely girl and her family; as he learns to feel and belong he uncovers the dark plot and misunderstandings that led to his fall and works to clear his name, blending myth, warmth, and wry humor in a tale about identity, loyalty, and redemption.
