Sylvia Sidney once offered Ger Orvedahl $2,500 for Tuffy. Ger turned her
down.
Tuffy's name is misspelled "Tuffie" in the credits of "Daredevils of
the Red Circle."
Scientists at UCLA tested Tuffy's intelligence. Tuffy passed the tests
with flying colors. Dr. Knight Dunlap declared, "He may not be the most
intelligent dog in the world, but he is certainly the most intelligent
I have ever seen."
Tuffy was taught some commands in different languages.
