In Oblivion yes it is a mod. In morrowind it is the bloodmoon expansion. In Skyrim its part of the fighters guild (companions) storyline
you cant in oblivion without a mod
I have tried it myself and it is great, I believe it adds werewolves to certain places of Cyrodil, and there is a ritual for becoming a werewolf. However in this mod the werewolves are called lycans. This mod also enables the opportunity for you to become a lich.
You can find a werewolf if you get the mods Curse of Hircine, Druid mod, or Legends of the North. In The Curse of Hircine, you can find a werewolf west of the Imperial City. At night, just follow the west path and then follow the path up. The werewolf should be around that area at night. With the Druid mod I'm pretty sure "Druid" is a class, and if not you just have it at the beginning at the game. With this you can turn into a werewolf at any time you want. With the Legends of he North mod, you will have a quest at the beginning of the game and you just do that quest. I don't think you can become infected by the werewolf of that mod though...
There are no dragons in Oblivion unless you mod them in.
It is a mod or a download.
