First of all, it is evolve, not involve. To evolve Growlithe you must give it a firestone
Vulpix, Growlithe, and Eevee.
Vulpix, Growlithe, Eevee, and Pansear.
You aren't able to evolve Growlithe by level, but you would have to use a fire stone to evolve it.
You can't catch it, you have to transfer it from a generation IV game.
You'll need to use a Fire Stone on it.
No. Growlithe is a Pokemon exclusive to Pokemon FireRed Version.
There aren't any Growlithe in Pokemon Ruby, but you can trade for them from Pokemon Fire Red or Pokemon XD.

Growlithe doesn't level up to evolve He / She need a Firestone to evolve, i'm not sure where you find a firestone i brung my Arcanine over from my Pokemon White game glad to answer...Veronica
Growlithe evolves into Arcanine when you give the Pokemon a fire stone.
I think it is only growlithe and arcinine.
You can find a Growlithe in the Pokemon mansion. This is in FireRed only.
