A new book, “Amazing Dogs,” by Dr. Jan Bondeson, a senior lecturer at Cardiff University School of Medicine in Wales, reveals that Hitler supported a German school that tried to teach large, muscular mastiffs to “talk” to humans. This story set off a panting spate of “Heel Hitler,” “Furred Reich,” “Wooffan SS” and “Arf Wiedersehen” headlines in British tabloids and plenty of claims that Hitler was “barking mad.”

“There were some very strange experiments going on in wartime Germany, with regard to dog-human communication,” Bondeson writes, wondering: “Were the Nazis trying to develop a breed of super-intelligent canine storm troopers, capable of communicating with their human masters of the Herrenvolk?”

He discovered a 1943 Nazi magazine piece about the headmistress of the canine school, a Frau Schmitt, claiming that some of the dogs spoke a few words. “At a Nazi study course, a talking dog was once asked ‘Who is Adolf Hitler?’ and replied ‘Mein Führer!” Bondeson writes of these claims, noting that “the Nazis, who had such conspicuous disregard for human rights, felt more strongly about the animals.”

Nazi propaganda dwelled on Hitler as a dog lover. He owned two German shepherds named Bella and Blondi. He tested a cyanide capsule on Blondi and killed her just before he committed suicide.

The Nazis took their dogs seriously. As The Guardian reported in January, the Nazi government was so furious about a dog in Finland that had been trained to imitate Hitler with a Nazi salute that the foreign office in Berlin started “an obsessive campaign” to destroy its owner.

Bondeson writes that in Germany in the early 20th century, some people had a strong belief in the potential of super-intelligent animals. He said that along with Thomas Mann and Hermann Hesse, an Airedale terrier named Rolf was considered one of the leading German intellectuals of the time. Rolf’s owner said she taught him his own alphabet with a system of taps of his paw on a board and, Bondeson notes drolly, “he successfully dabbled in mathematics, ethics, religion and philosophy.”

The latest wacky Hitler story comes from the British author Graeme Donald. He says that, while researching a military book, he stumbled across a story that Hitler and Heinrich Himmler were so worried about German soldiers’ getting sexual diseases from French hookers that they cooked up a plan for soldiers to carry small blow-up blond, blue-eyed dolls called “gynoids” in their backpacks to use as sex “comforters.”

Donald said Himmler ordered 50 dolls but the soldiers were too embarrassed to carry them. “In the end the idea fizzled out,” Donald told The Sun, “and the place where they were made and all the dolls were destroyed in the bombing of Dresden.”
