In The Wonderful Wizard of Oz, Baum did not specifically state Toto's breed, but describes him as "a little black dog (male although he was played by a female dog in the 1939 MGM movie) with long silky hair and small black eyes that twinkled merrily on either side of his funny, wee nose".
Considering this, what breed was Toto from the Wizard of Oz?
Cairn Terrier
Considering this, what does Toto in The Wizard of Oz represent?
In The Wizard of Oz, characters like Glinda the Good Witch represent the mother archetype because she looks out for Dorothy, and Toto represent the trickster, because he is always creating problems.
After her immortal role as Toto, Terry appeared in a half-dozen other films. In 1942, three years after The Wizard of Oz, Terry's name was officially changed to Toto. Terry died in 1945 at the age of 13 (that's 91 in human years).
