Murphy, a Tibetan Terrier puppy, is told he is a 'good luck dog' - he is cheerful, happy, and loves to play and wag his tail. However, after going through two different homes and an animal shelter, Murphy starts to feel like a 'bad luck dog' who nobody wants. Murphy's Three Homes follows this adorable pup through his placement in three new homes, as well as through his anxiety, self-doubt, and hope for a new, loving family. Finally, Murphy is placed in a caring foster home where he feels comfortable and valued. He learns that he is not a bad dog after all and can go back to being a playful puppy and a 'good luck dog!'
