Hisuian Growlithe's soft and insulated fur allows it to survive the cold weather of Hisui. Growlithe rarely uses its horn unless needed due to it being easily broken. A pair of Hisuian Growlithe are known to be vigilant when guarding territory. Hisuian Growlithe take much longer to bond with humans because they have lived apart from humans for many years.[1] Growlithe's Hisuian form is the result of it being exposed to volcanic activity within the coastal highlands it lives in during Hisui.
