How do you raise dratini faster in Pokemon FireRed?

Give it the Exp. Share -- Or do what my friends do, trade it to another Pokemon game, give it Exp. Share, battle with it in the other game; because he is a traded pokemon, he will gain more experience in battle. When it goes up the desired amount of levels trade it back to your game. He will obey you regardless of level, he could be level 100 and he will obey you because he is yours!
