It doesn't evolve by level, you can use a fire stone on growlthe at any level to make it evolve.
Growlithe evolves via Fire Stone and not level up.
Growlithe doesn't evolve by level, but with a Fire Stone
It does not evolve by level, it evolves by using a fire stone. If you have the choice, i would go with growlthe over vulpix though.
Growlithe cannot level up to Arcanine, you must get a Fire Stone from the Celadon City PokeMart. Good Luck!
Growlthe Evolves Into Arcanine, a really strong Dog Pokemon. You can only evolve it with a Fire stone
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.
It is suppose to evolve at the Level of 20,but if you want it to evolve later it can evolve anything after it is at Level 20.
