When Tom Corwin’s golden retriever, Bob, passed away unexpectedly, Tom decided to write a letter as a tribute to his life, which would also tell Bob’s many human friends what they might not have known — the surprising story of how Bob was once a ferocious, abused, untrusting dog named Red, and how he changed completely to become Tom’s best friend. Once he sent the letter out, Tom began receiving an outpouring of heartfelt responses to what he thought was just a slightly unusual story about his dog, but was, he came to realize, a universal tale about the possibility of change and the power of love with no strings attached. Friends and strangers urged him to bring the story to more people, and with a vision of how it might look, Tom designed and made by hand a special book version of the letter, complete with flipbook illustrations of his beloved Bob.
