Thank you for the replies. We intend to put him into a basic puppy obedience class.

Yes, I am alpha over the alpha dog. I am firm enough and persistant. Most of the time, he'll put his ears back and give kisses, now he just bites and growls more. I don't know what started that.

I will definitely look into a certified behaviorist.

Do you think there is anything MORE I should be doing? Or am I doing something wrong? Thanks ahead of time for any suggestions and responses.
