Hollywood icon Betty White and actor Tom Sullivan present the story of a guide dog named Dinah and the extraordinary difference she made in every life she touched. Beloved actress Betty White is a bona fide television pioneer, but throughout her life, her heart has always been with the animals. One of the most enriching episodes in her career as an animal-rights advocate arrived with actor Tom Sullivan. Blind since birth, Tom was one of Betty's closest friends and professional partners. Their dearest collaboration was a mutual devotion to a golden retriever named Dinah.  This first-class guide dog was more than Tom's best friend, she was a source of unqualified loyalty and love. Most important, she enabled Tom to be truly independent for the first time in his life. However as Dinah got older, as her faculties weakened and her confidence faltered, Tom had little choice but to get a new dog. The effect of losing her purpose was devastating to the once-gallant Dinah. Then Betty gladly stepped in to give this great Lady a new lease on life. What would transpire is a heartening and inspiring story of a dog who made a difference and who, in Betty White's words, "helped Tom grow up as she has helped me grow older." It is for all animal lovers, for all Betty White lovers, and everyone who can relate to the unconditional devotion of dogs and the people who love them.  INCLUDES PHOTOS
