New documents: Hitler-mocking dog enraged Nazis Historians had not been aware of the strange footnote to the Nazi period before some thirty files containing parts of the correspondence and diplomatic cables were recently found by a researcher at the political archives of the German Foreign Office. Klaus Hillenbrand, an expert who has written several books on the Nazi period, was contacted by the historian and examined all of the documents for an article to be published Saturday in daily newspaper Die Tageszeitung. In an interview with The Associated Press, Hillenbrand called the entire episode "completely bizarre." "Just months before the Nazis launched their attack on the Soviet Union, they had nothing better to do than to obsess about this dog," Hillenbrand said. The dog, Jackie, was a mutt owned by Tor Borg, a businessman from the Finnish city of Tampere. Borg's wife Josefine, a German citizen known for her anti-Nazi sentiments, dubbed the dog Hitler because of the strange way it raised its paw high in the air like Germans greeting the Fuehrer with a cry of "Heil Hitler!"
