Hello all.

I wanted to thank you all for your many responses and for being very, very helpful. I also wanted to apologize for not writing this sooner. One helpful thing that the local trainer told me is, when he bites, put him on his back, to MAKE him be submissive. Keep him there until he starts giving kisses or calms down. My pup has definitely improved in most things, but we have found out he is food aggressive, but slowly learning not to be. He still gets an attitude, but knows it's wrong. He can't seem to help himself. We've also used the spraying water method when he bites us. Of course, not to hurt him, but he doesn't like it and has made the connection. Overall, has improved so much and I want to thank you all again for your helpful replies. He is enrolled in a puppy class that has not yet started. We love him very much and I can't believe how big he's gotten!

Attached is the lastest picture of him.
He is 3 months old now.
