No
you dont find the legendary dogs in fire red. instead you get the legendary birds. they are zapados moltres and articuno
None of the legendary dogs are available in Emerald you must obtain them from Firered, Leafgreen, or Pokemon Colosseum.
migrate from firered and leafgreen
no you cant and how would that even work.
gatch them with a master ball but trade the master balls
If you chose Bulbasaur, you'll find Entei. If you chose Squirtle, you'll find Raikou. If you chose Charmander, you'll find Suicune.
The only way to get the Legendary Beasts in Pokemon Pearl is to find them in FireRed, LeafGreen, HeartGold or SoulSilver, catch them and then migrate them over to Diamond via Pal Park.
The legendary Dogs in FireRed( Entei, Raikou, and Suicune) are found randomly. If you started off with cHarmander as your starter then you will find Suicune in the wild. If you picked Squirtle as your starter then you will find Raikou and if you picked Bulbasaur as your starter then you will find Entei. You can find them in the grass and on the water. I'm not sure about caves. P.s. If you trading with other players and get all three starters then you can catch al three of the legendary dogs!!!!!!!
Zapdos arcticuno moltres
Deoxys is a legendary Pokemon which has various different forms. To find one in FireRed version, you need to have an Aurora Ticket.
you have to beat the elite four then look in the grass and hope you find the legendary dogs
You need to migrate each from either firered or leafgreen or you can trade with heartgold and soulsilver after they got them.
