Goebbles wrote in his Diary, May 30 1942;
“He (Hitler) has bought himself a young German Shepard dog called “Blondi” which is the apple of his eye. It was touching listening to him say that he enjoyed walking with this dog so much, because only with it could he be sure that [his companion] would not start talking about the war or politics. One notices time and time again that the Fuhrer is slowly but surely becoming lonely. It is very touching to see him play with this young German Shepard dog. The animal has grown so accustomed to him that it will hardly take a step without him. It is very nice to watch the Fuhrer with his dog. At the moment the dog is the only living thing that is constantly with him. At night it sleeps at the foot of his bed, it is allowed into his sleeping compartment in the special train and enjoys a number of privileges….that no human would ever dare to claim. He bought the dog from a minor official in the post office in Ingolstadt”
