All I know of is Arcanine
Dratini can't learn Extremespeed in LeafGreen, but can learn it through breeding and as a prize in Crystal, HeartGold and SoulSilver. After answering all the Dragon Master's questions correctly in the Dragon Shrine, a Dratini with Extremespeed will be given as a prize.
Growlithe cannot learn extremespeed.
it is very rare that a furret can even learn extremespeed.
Arcanine learns Extremespeed at Lv. 49, which is the same level that Growlithe learns Flamethrower. So, if you want Flamethrower and Extremespeed, use the Fire Stone on Growlithe only at level 49.
You can get it at the goldenrod department store
at level 51 it will learn extremespeed
you cant
Arcanine doesn't learn flamethrower in any Pokemon games, if you want to teach him, give him the TM flamethrower (TM35). However, if you waited till lv 50, a growlithe can indeed learn flamethrower on its own. Unfortunately, arcanine would not learn extremespeed as a result. Ah but it does, if you get it up to level 50 it will learn flamethrower then evolve it using a fire stone and when it has evolved it will learn extremespeed soz if answer is a bit late
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.

Go to pastoria talk to the move tutor and give him a heart scale
togekiss cannot learn any moves naturally, it can only learn with heart scale(move tutor), it can learn extremespeed, air slash, sky attack and aura sphere, but it is a terrific HM slave, and can learn a variety of moves
