You cannot get a Suicune Egg in Pokémon SoulSilver. Suicune cannot breed.
you must then go past the bridge in cerulian city to the end there you will find suicune it will not flee and it is level:40
Suicune is on Route 25.
Suicune is at Level 40 in HeartGold and SoulSilver.
After you defeat Misty, You can go catch suicune by Bill`s house.
After you get to Kanto and talked to Eusine, go to the cape outside of Cerulean.
The legendaries on Soulsilver are as follows: Entei, Raikou, Suicune, Lugia, Ho-oh, Groudon, Latios, Rayquaza, Mewtwo, Moltres, Articuno, Zapdos. These are the legendaries found on Pokémon Soulsilver version. ~CareyPrice31FTW
It's your opinion, but in HeartGold you can catch Ho-oh, Suicune, Raiku, and Entei, and in SoulSilver you can catch Lugia, Zapdos, Moltres, and Articuno. There are also more Pokemon available in HeartGold than SoulSilver. Edit: The person who last answered this question is wrong, you can catch all of the above Pokemon in both games, not in either or. I know this because I have soul silver and I have suicune, raiku, Entei, Ho-oh, Lugia, Zapdos, Moltres, and Articuno; so obviously you must be able to catch them in both.
You can't catch bastiodon in Pokemon soulsilver.
there isn't a wild suicune to catch in white or black
