Pokemon Black and White help please?

So now I got my event Celebi from GameStop yesterday and the game Pokemon Black. When do I get to catch Zorua and Zoruark and I aslo have the trio shiny dogs from Johto. Also if anyone would like a pokemon battle in Black or White my friend code is: 0346 8584 4963. Even though I'm not too far into the game, I just aquired my 6th gym badge.
