Toto is a fictional dog in L. Frank Baum's Oz series of children's books, and works derived from them. His name is pronounced with a long "O", a homophone of "toe toe". He was originally a small terrier drawn by W. W. Denslow for the first edition of The Wonderful Wizard of Oz (1900). He reappears in numerous adaptations, such as The Wizard of Oz (1939) and The Wiz (1978).
