A boy gets turned into a dog after mispronouncing a wish to a shooting star following some questionable advice from a hobo named "the professor." That line is "Wishing star, I want...ah! A bee!...a dog for christmas," and the writing doesn't get much better from there! The plot follows the boy turned dog's hijinks, and we meet characters like the old women who thinks the dog's her relative reincarnated, the neighbors who drive 100 miles to find a christmas tree and take the dog along, and a fight between a nobel mountain lion and a bear... with reaction shots of a dog nowhere near that national geographic stock footage.
