A dog called Laika.
Not as far as anyone knows. The next launch, Sputnik 2, carried a dog called Laika.
Because the Sputnik program ended with Sputnik 3. Albeit there was a Sputnik 40 and 41 but these were to commemorate the 40th anniversary of Sputnik 1.
The dog, Laika, died due to temperature increase.
The first sputnik didn't actually crash but rather burned as it reentered the atmosphere in January of 1958. There were actually over 40 sputnik's released into space.
The dog on board - Laika - died, presumably from heatstroke.
The Soviet Space Program later replaced by the Russian Federal Space Agency have officially named 12 Sputnik craft (Sputnik 1 through Sputnik 10 which were launched by rockets into orbit as well as Sputnik 40 and Sputnik 41 which were released from the Mir space station). Outside of the Soviet Union, Sputnik 20 through Sputnik 25 may be referred to. However, the Soviet Union officially refers to these as Cosmos missions due to the launch failures.
As far as we know, it didn't. But if you can launch something harmless into orbit, you can also launch something dangerous into orbit, which was a big part of the fear caused by the Sputnik launch.

Not sure what you're asking... technically Sputnik was a part of the Russian space program (like Apollo was part of the U.S. space program). Sputnik in Russian literally means "co-traveler" or "satellite".The program started in 1957 with Sputnik 1 (about 23 inches in diameter, weighing in at about 183 lbs). Sputnik 2was a 13' by 6.6' cone shaped capsule, large enough to carry the first living animal in space (a dog named Laika). Sputnik 3was a slightly smaller cone (11.7' x 5.6').
