You can't find them in Yellow at all. Entei, Raikou, and Suicune weren't introduced until the 2nd generation games (Gold/Silver/Crystal).
You can't. The legendary dogs didn't exist at the time yellow was released. Sorry.
No
you have to beat the elite four then look in the grass and hope you find the legendary dogs
you dont find the legendary dogs in fire red. instead you get the legendary birds. they are zapados moltres and articuno
Jirachi, a legendary Hoenn Pokémon, is unobtainable in Yellow.
the basement
you find the legendary dogs in tall grass!
The closest thing to Poke gods would be the "Legendary" Pokemon, like the Legendary Birds in Red, Blue, and Yellow, or the Legendary Dogs, of Gold, Silver, and Cystal.
You can find Lugia, the legendary dogs/ Suicune, Enti, and Raichu, and I think Ho-Ho
maybe the 3 legendary dogs i think but there is a chance to be pikachu if its in level 81
you find them roaming in the grass
it depend upon ur starter
