Dragonite doesn't learn extreme speed through level up, nor from other pokemon by egg breeding. The only way to get a Dragonite with extreme speed is from HG/SS version in Dragon's Den, after giving the old geezer guy inside the right answers for his test. If you answer correctly he'll give you a Level 15 Dratini with extreme speed. However, giving him a slightly wrong answer he'll give you a regular Dratini.

at level 51 it will learn extremespeed
they dont
He cant learn any moves after you evolve him from growlithe with a firestone. -Wirets Edit- You are wrong, Arcanine can learn moves after you evolve it. At level 33 it can learn Extreme speed.
Only its former evolution, Growlthe, can learn it before it. When you evolve Arcanine, it cant learn ANY of growlthes moves, but can learn extreme speed at level 33. Or you could just teach Arcanine flamethrower by using the TM flamethrower, otherwise, you will have to level up a growlithe until it learns flamethrower then evolve it into an arcanine.
Growlithe does not learn Extremespeed, only its evolved form, Arcanine, learns Extremespeed at level 49. Note that this is the same level that Growlithe learns flamethrower, which Arcanine can only learn through a TM, so if you want both Extremespeed and Flamethrower, evolve Growlithe at level 49.
