Both of these Pokémon are Hisuian forms - new regional variants introduced in Legends: Arceus - and, due to this, are fire and rock-types rather than the traditional pure fire-types of their Gen 1 forms. Below you’ll learn how to evolve Hisuian Growlithe into Hisuian Arcanine, along where to find Hisuian Growlithe if you haven’t caught one yet. On this page: If you’d like to learn more about the game, visit our Pokémon Legends: Arceus walkthrough. Within the Cobalt Coastlands, you’ll be able to find Hisuian Growltihe’s in the Windbreak Stand and Veilstone Cape locations. You will need the Sneasler Mount Pokémon to reach the higher level Hisuian Growlithes. Any Hisuian Growlithe you catch can be evolved into a Hisuian Arcanine at any time if you happen to have a Fire Stone. So how do you get one? Our Pokémon Legends Arceus walkthrough will help you pick a starter Pokémon and win the Kleavor boss fight. You’re also tasked with filling the Hisui Pokédex by obtaining new evolutions like Kleavor by evolving Scyther, Wyrdeer by evolving Stantler, Sneasler by evolving Hisui Sneasel and Overquil by evolving Hisui Qwilfish. There’s a host of new evolution methods, including ones for the Eevee evolutions. Take the time to complete Requests too, such as The Sea’s Legend, Wurmple’s Evolved! and finding the Wisp locations. Don’t forget to track down every Unown location too. You can also find Fire Stones by breaking the Red Tumblestone Crystals which are scattered all across the Hisui region. Since Tumblestones are essential to multiple Poké Ball recipes, we recommend using this method over spending your precious Merit Points. You’re going to be breaking an awful lot of these crystals after all! Finally, you might find one on the ground in a Space-time Distortion. If you’d like to learn more about evolution methods in Legends: Arceus, visit our guides on the Eevee evolutions, along with how to evolve Stantler into Wyrdeer, Hisui Sneasel into Sneasler, Johto Sneasel into Weavile, Hisui Qwilfish into Overqwil, Scyther into Scizor, Scyther into Kleavor and how to get Black Augurite. Good luck in the Hisui region!
