"Golden Girls" star Betty White has written the biography of a seeing-eye dog. "The Leading Lady: Dinah's Story," is about a seeing-eye dog who used to belong to White's friend, Tom Sullivan, the blind actor. When Dinah was retired from seeing-eye service, Sullivan gave her to White. "Although we didn't work together, Tom and I wrote alternating chapters. It took me a year and a half and the results have been wonderful," said White.
