That was Laika, Dixie.
Here's some more info on dogs in space.
"Dezik and Tsygan were the first dogs to make a sub-orbital flight on July 22, 1951.
Both dogs were recovered unharmed after travelling to a maximum altitude of 110 km. Dezik made another sub-orbital flight in September 1951 with a dog named Lisa, although neither survived.
However, the name of the dog (and indeed the first living creature) to go into space and orbit the Earth was Laika, and she was launched into space on board a Soviet spacecraft 'Sputnik II' (the launch vehicle was the Soviet R-7/SS-6 ICBM (Inter Continental Ballistic Missile) ) on November 3rd 1957.
Laika, [Лайка] means "barker" in Russian (her name was originally Kudryavka). She was said to have died painlessly in orbit about a week after blast-off. However, she did not live nearly as long as Soviet officials led the world to believe. Now, it has been revealed she died from overheating and panic just a few hours (maybe as few as 3) after the mission started."
