The Princess and the Pawper by Daniel Boey

When Luke was rescued, he was very skinny and malnourished, with flaky skin, patchy fur and the saddest eyes, red from crying himself to sleep every night. And he was smelly from not having showered for a very long time. Everywhere he went, people would make unkind, snide remarks about him. Till he was rescued by the princess, Leia. This is the incredible story of how a sickly, scruffy pawper, saved from a miserable caged life, found the strength and courage to bounce back through selfless love, kindness and compassion to become the toast of the town. A book in the Furry Tales by Leia series.
