Yes, you can catch the shiny version of Growlithe in Pokemon GO, but it is very rare.
Any Growlithe you encounter in the game has a very low chance of being shiny, whether you find one as a wild spawn or earn a Growlithe encounter as a reward through Research.
If you are after a shiny Growlithe, the best time to catch one is during the Pokemon GO Growlithe Spotlight Hour on September 26, 2023. This is because Growlithe will be spawning in the wild much more frequently, giving you dozens of opportunities to find the shiny version!
Growlithe Shiny Odds in Pokemon GO
The odds of any Growlithe you encounter in Pokemon GO being shiny is 0.2%. This means that, on average, you’ll need to encounter 500 Growlithe before finding a shiny version.
Unfortunately, there is no way to increase the shiny rate in Pokemon GO, so you’ll have to keep encountering plenty of Grlwothie until you find this rare shiny!
What Color is Shiny Growlithe?
The shiny version of Growlithe is a very bright yellow color with black stripes and has light yellow fur on its head, body, and tail.
This makes it stand out from the orange standard version of Growlithe.
