Doduo evolves into Dodrio at level 31. http://www.serebii.net/pokedex-rs/084.shtml
It does not evolve at a certain level. It evolves when you use a Fire Stone on it.
Lvl 20.
beet the league,get the national pokedex get full friendship then evolve it one level
Personally i would say as soon as you get gloom evolve it.
Sandshrew evolves at level 22 in both fire red and leaf green. But in order to get sandshrew on fire red version, you have to trade it
If you mean flareon, then i will tell you. Flareon does not evolve. It evolves using a fire stone and it can't evolve after that.
In Pokémon FireRed, you can find Dodrio by evolving a Doduo, which you can catch in the Safari Zone. Once you have a Doduo, level it up to level 31, and it will evolve into Dodrio. Alternatively, you can trade for Dodrio with another player or find it in the wild in certain locations in Pokémon Emerald or LeafGreen, but it's not directly available in FireRed.
AT level 50 this is a good website for all Pokemon and what they evolve into http://bulbapedia.bulbagarden.net/wiki/List_of_Pok%C3%A9mon_by_evolution_family
Level the Pokemon you want up to a specific level, or link trade it with another player and it may evolve. Don't forget to get it back though!!!
