Depends on which game you're asking about. In Gold, Silver, and Crystal, Suicune can be caught any time after being released, so you can battle it before Ho-Oh. In Crystal, you have to battle Suicune first before you can battle Ho-Oh. In HeartGold, you can't, as you're required to battle Ho-Oh first. In SoulSilver, you can, as you get the Rainbow Wing at Pewter City.
to catch any of these u need either a gameshark or use other cheats.
You can catch Suicune using any type of pokeball. The best odds of catching it come with the ultra ball. If you use a master ball, it is a certain catch. Any other ball has less odds.
After catching all the legendary dogs Suicune, Entei and Raikou Ho-oh will appear in tin tower situated in ecrutek town. Also I think you might need the Rainbow Feather
I guess you could find and catch either latios or latias , go to the trainer house in Viridian City or try to complete the national Pokemondex. Or if you didn't end up catching suicune go to the burned tower and catch it there.
there isn't a wild suicune to catch in white or black
You can get any starter to catch Suicune.
yes
Use a Master ball on Suicune but there is an easier way get Suicune. Catch a Pokemon who has the ability of spell tag.
Suicune is a hard Pokemon to catch Suicune will move around diffrent places. You normally catch Sucune at level 40 use your map to try and find Suicune on your pokegear. It is hard but you will get there
You can catch Suicune at many points in the game. It depends on when you caught it. It is impossible to say what you must do next.
you cant...sorry
yes
