Arcanine is a Fire-type Pokémon that can be obtained through using a Fire Stone on a Growlithe. It should be noted that the only move that Arcanine will learn after it has evolved is ExtremeSpeed at level 34. Because of this, it is highly recommended you wait until your Growlithe has learned strong Fire-type moves before evolving it. To stop the evolution and pro-long it, simply click on the "cancel" button which you are given just before the Pokemon evolves. Arcanine is not obtainible in nature but can be gotten from the Fire Stone method above or by trade for it from another person.
