It won't until they release it from the dogechain.  Look up your transaction and you will see something like not yet redeemed. Exchanges work kind of like escrow systems.  You send money to an address, the TX is stored in the chain with the address you sent it to untill the other party accepts the TX, releasing the funds to move to deposit status.  I think the good exchanges have this on auto, then it's only the confirms you wait for.  Cryptsy puts it in a que that obviously processes one TX at a time and waits for confirms, then the next, then the next.......  No batch processing run as a cron job.  Poor network management imo.
