1. Route 44 (After the 4th Gym):
* This is the most common way to get a Growlithe. After defeating the 4th Gym Leader, Morty in Ecruteak City, head to Route 44, the path leading north to Olivine City.
* Growlithe will appear randomly in the tall grass on this route. They are not too rare, but you may need to battle a few Pokemon before you encounter one.
2. Trade:
* You can trade for a Growlithe from another player. This is the most reliable way to get one if you're having trouble finding it on Route 44.
* You can also try trading with players online.
3. Breeding:
* You can breed a Growlithe with another Pokemon that can learn the move "Flame Body" (like Houndour).
* The offspring will inherit the Flame Body ability, giving it a higher chance of hatching with a Shiny Growlithe.
4. Find a Shiny Growlithe:
* You can try to find a Shiny Growlithe in the wild. This is very rare, but if you're lucky, you might come across one.
Tips for catching a Growlithe:
* Use a Pokemon that knows "Thunder Wave" or "Sleep" to paralyze or put the Growlithe to sleep.
* Throw Pokeballs to capture it, starting with a regular Poke Ball and working your way up to Great Balls and Ultra Balls if necessary.
Note: Growlithe evolves into Arcanine at level 30.
