Thanks everyone for your helpful advice! I made a HUGE mistake in my original post... Rocky is 11 WEEKS old, not months! I can't believe I wrote that!
I have called a local dog trainer who I have heard rave reviews about. He is coming to our house for a consultation. Also, we will be starting him in some puppy classes the next time a round starts.
He can be a sweetheart, don't get me wrong! I love him to pieces! He seems to really listen to and obey my husband... at least considerably better than me! I don't get it because we do the SAME things. My husband thinks it's laughable... I don't find it so funny

I am just afraid to say oh it's puppy behavior and then be suprised later when he bites a child (heaven forbid!).
He is not the puppy who bit another child. This incident that I wrote about is the first and only serious biting incident.
Thanks again for all of your advice and keep it coming
