unfortunately you can't catch all 3 however depending on the starter you chose lets say its bulbasaur then you will find entei, if you chose squirtle you get raikou, and charmander gets you suicune.
i don't know about gold and silver but in crystal you catch suicune in a standard battle at the tin tower ant raiku and entei will be in the wild but will always run from you
Articuno, Moltres, Zapdos, Ho-oh, Lugia, Raikou (starting with squirtle), Suicune (starting with charmander), and Entei (starting with bulbasaur)
You have to defeat the elite four and you will only get one depending on your starter. Either Entei (Bulbasaur), Suicune (Charmander), or Raikou (Squirtle) will appear. They are all at lv. 50, and are very hard to meet and catch.
Umm i think there are three: entei, raikou, and suicune. but its probably just suicune
There is actually nothing you do with Entei, Raikou, and Suicune (Being a legendary dog-catcher myself,). Just the pleasure (Not really) of having the three.
You chase Entei and Raikou across Jhoto and you catch Suicune at the top of Cerulean City.
yes, if you have entei raikou or suicune.
to catch suicune,mewtwo,raikou and entei
You can't. You have to migrate from LeafGreen or FireRed.
ho-oh, lugia, suicune, entei, raikou
You have to trade or migrate. You can't catch them in diamond.
if you have firered or leafgreenyou will be able to catch entei ,raikou, suicune only if you beat the elite four then when you catch the three lengendaries then migrate then into Pokemon diamond

You can catch Mewtwo, Suicune, Entei, Raiku, Ho-Oh, and Lugia.
