What Breed of Dog was Toto?

In the actual book ‘The Wonderful Wizard of Oz’, the author Frank Baum did not specify what breed of dog Toto was. In the book the illustrators chose a cairn terrier to represent him. The movie used a Cairn Terrier named Terry. Interestingly, Toto was paid more per week than any of human munchkin actors. You can find more information here:
