Blondi (1941 — 29 April 1945) was Adolf Hitler's pet German Shepherd dog. She was given to him as a gift in 1941 by Martin Bormann. Blondi stayed with Hitler even after his move into the Führerbunker located underneath the garden of the Reich Chancellery on January 16, 1945. In March or in early April (likely 4 April) 1945, she had a litter of five puppies with Gerdy Troost's German Shepherd, Harras. Hitler named one of the puppies "Wolf", his favorite nickname and the meaning of his own first name, Adolf (Noble wolf) and he began to train her. One of Blondi's puppies was reserved for Eva Braun's sister Gretl, and Eva sent Gretl a letter containing a photo of Blondi and three of her puppies, Gretl's being indicated with an arrow.
