Because 'back in the day' there were no cars or anything so instead of dogs to pull a sleigh they needed something to get height so they used reindeer ;)
Rudolph was the last to join the sleigh-pulling team, because when I read an old English version of The Night Before Christmas, there were only eight reindeer pulling Santa's sleigh.

NO! i want to know WHY only 7 reindeer?
He's not as well known for pulling Santa's sleigh as much as he is known for LIGHTING THE WAY!
Rudolph, he got added later on in history. If that's not the answer, then sorry.

Male reindeer drop their antlers in early November. ALL pictures of Santa's reideer show them them to have antlers ,while pulling Santa's sleigh, in December.
On his sleigh? Reins. Santa puts reins on his reindeer that are attached to his sleigh. :D
Reindeer
It's a sleigh (large sled) but don't think it has another name
