The story of a dog, and the extraordinary difference she made in every life she touched. After sixty years in show business, Betty White has earned her reputation as an American icon. She may be a bona fide television pioneer, but throughout Betty’s life, her heart has always been with the animals. But 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.
