The lead dog, Petunia, was actually rescued from an animal shelter to play the role in 12 Dog Days Till Christmas. She had very little hair initially, but by the time filming started she had grown back a lot of her hair due to the love and attention she received in her new home. She is still living with the animal trainer after the film.
