I could not find a definite answer for you regarding the handkerchief used to hold off the military dogs in WWII. But I happen to know a little about the story on them. The fishermen used the handkerchief to guard off the dogs that were used to find people hiding in boats. The dogs would smell something on the handkerchief and go to sniff finding his nose numb. The handkerchief had blood and cocaine on it. Blood to attract the dog. Cocaine to numb the dog's nose. If you want more information on this, at the end of the book, Number the Stars (by Lois Lowry) it tells more about. I have added some links for your further research.
