First understand, Bo is still a puppy who doesn't know any better. He needs to be taught what is exceptable and what isn't. Just like you would a child. He needs to be supervised by an adult at all times. (Not sure how old your niece is) And you are right, petsmart classes are useless.
Are you using NILF with him? If not, I would suggest starting that right away. Also start having everyone start taking things from him and be there to correct him if growls or snaps. I've always used the "no bite" techinque.
The main thing to keep in mind, is that he is still a baby and testing his bounderies.
