Unfortunately you can't. To get it you have to trade someone who has one. In Fire Red for example.
You can't get a growlithe in Soul Silver. You must trade it from a Heart Gold or other Pokemon game. Vulpix can be found in Soul Silver but not in Heart Gold.
Growlithe can't be found in soul silver. Its only in heart gold. Vulpix is in soulsilever, growlithe is in heart gold, there like counter parts
Trade

Growlithe will evolve when you use a fire stone on it.

Growlithe will evolve when you use a fire stone on it.
