Novelization
While the movie itself is based on Salten's The Hound of Florence, a novelization of the movie published by Scholastic eight years later in 1967 made some interesting changes to the plot. First, Funicello's character Allison was removed entirely, and her name is not listed among the movie's principal performers. As a result, the rivalry between Wilby and Buzz is greatly reduced. Also, Dr. Valasky is changed into Franceska's uncle, not her adoptive father.
