"Canis Lupis vulcanis"
Call: a series of growls, howls, barking and whimpering
Diet: mainly carnivorous, but will eat some fruits, such as pecha berries
Range: high mountains and forests, often found near the calderas of active volcanoes. Mainly in the Kanto region.
Relatives: closely related to houndour/houndoom, other relatives include vulpixes/ninetales and eevees (including their evolutions)
Arcanines are actually an altered form of the growlithe. This happens because of a slight change in DNA caused by a stone with weak radioactive properties (fire stone). After exposure to a fire stone, a growlithe's body mass dramatically increases and it grows more hair. These stones are on rare occaisions found in the high mountains where the arcanines and growlithes live.
Arcanines and growlithes, like most dogs, live in family oriented packs. The arcanines are respected by the rest of the pack and are considered the alpha dog. If the pack is attacked, the alpha dog defends its family with a variety of physical and elemental attacks.
Growlithes and arcanines have a gland in their throat that produces a hydrocarbon slurry. This can be sprayed out their mouth, which causes it to pass a tiny, heat-producing spike that ignites the slurry. This attack can be a stream (known as flamethrower) or one large burst (known as fire blast). Younger dogs tend to have thicker slurry that comes out in flaming clumps, which is an early attack known as ember. Though they do not learn it on their own, growlithes and arcanines can be taught overheat.
The fur and skin of growlithes and arcanines does not burn because it is covered in a flame-retardant fine powder. The throat and tongue are extremely thick compared to other dogs. Owners are urged not to bathe their arcanines and growlithes unless with a special dry shampoo, or else this powder may be temprarily lost and their fur may burn.
