In every Pokemon game, there are certain Pokemon that are more popular than others and it looks like in Legends Arceus, two of those Pokemon will be Hisuian Growlithe and its evolved form Hisuian Arcanine.
Hisuian Growlithe was one of the first new Pokemon revealed in the game and fans fell madly in love with its giant fluffy mane and cute little horn.
It was from this moment that Hisuian Growlithe was destined to become one of the most popular Pokemon in Legends Arceus.
To help you out, here is exactly how you evolve Hisuian Growlithe into Hisuian Arcanine in Pokemon Legends: Arceus.
How To Evolve Hisuian Growlithe into Hisuian Arcanine in Pokemon Legends: Arceus
Much like it does in the mainline Pokemon titles, Hisuian Growlithe requires a special evolution method to become Hisuian Arcanine and sadly, just levelling it up won't do the trick. Thankfully, however, the actual method is probably even easier than that.
To evolve Hisuian Growlithe into Hisuian Arcanine in Pokemon Legends: Arceus players will need to use a trusty Fire Stone.
Once you have acquired both a Fire Stone and a Hisuian Growlithe, you will need to go into your items and use it on the Pokemon.
Where To Get a Fire Stone in Pokemon Legends: Arceus
Fire Stones can be acquired from the Trading Post in Jubilife Village prior to being used on Hisuian Growlithe.
To purchase a Fire Stone, you'll need to have earned 1000 Merit Points by completing a range of different requests throughout the game.
