SECRET documents have revealed how Germany was infuriated by an anti-Nazi dog that mimicked Hitler.
The Finnish dog would raise a paw in a mock-Nazi salute whenever its owner shouted "Hitler!"
Newly discovered documents show how Berlin's High Command plotted in 1941 to destroy the owner's business in revenge.
Historian Klaus Hillenbrand, an expert on the Nazi period who examined the documents, called the 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," he said.
The dalmatian mix named Jackie was owned by Tor Borg, an anti-Nazi businessman in Finland.
In one photo, Mr Borg appears with Jackie by his side wearing a pair of round sunglasses. A probe into the Hitler parody was carried out by the German Foreign Office, the Economy Ministry and even Hitler's Chancellery.
Mr Borg apologised and he -- and Jackie -- both survived the war.
