What did Hitler do to his wife and dog?
Hitler killed himself on the 30th April, 1945, with his wife,
one day after he married Eva Braun.
He killed his dog the day before on the 29th April, 1945.
Adolf Hitler knew that it was not long until the Russians
invaded his bunker, so rather than allowing the Russians (Who were
reported to be very brutish towards their prisoners) have his dog
(where it would have been unsafe) he gave it a cyanide pill.
The day after, Hitler and his new wife, Eva both took a cyanide
pill, Hitler shot himself in the head with a 7.65 mm Walther pistol
as well.
Hitler's soldiers then burnt his body so that the enemy could
not tamper with it.
