Toto is the name of a fictional dog in L. Frank Baum's Oz series of children's books, and works derived from them.
Toto belongs to Dorothy Gale, the heroine of the first and many subsequent books. In the first book, Toto never spoke, although other animals, native to Oz, did. In subsequent books, other animals gained the ability to speak on reaching Oz or similar lands, but Toto remained speechless. In Tik-Tok of Oz, continuity is restored: Toto reveals that he is able to talk, just like other animals in the land of Oz, and simply chooses not to. In The Lost Princess of Oz, he talks a great deal. Other major appearances include The Road to Oz, The Emerald City of Oz, Grampa in Oz and The Magical Mimics in Oz, in which he is the first to recognize the Mimics.
