Yeah I would hardly say your 8 week old puppy is aggressive.. just a landshark! Read the thread that David Winners posted and take note.. It will not last.. as with the "growling" I'm not there so I don't know, but I'm gonna guess he's a vocal little guy and that is he way of playing.. I have friend with dogs that get excited and make all kinds of noises that, if you didn't know better, you'd think they were fighting.
