History
Maple is Dorian's pet Cairn Terrier and best friend. In the beginning of the movie, she is trouble for chasing the cat of Dorian's nasty neighbor, Mister Almer Gump. When Mr. Gump shows up, he threatens to file a lawsuit to take the Gale farm away if Maple isn't given over to him and the sheriff. Aunt Em and Uncle Henry have no choice but to hand over Maple to him, despite Dorian's protests. While riding to the sheriff, Maple manages to slip out of the basket in the back of Mr. Gump's bicycle and runs back to Dorian, who is happy to have her back.
