Golden Retriever keeps chewing on furniture?

I have a one year old Golden Retriever male. When he was a young puppy he would chew on anything made of wood or the drywall. He eventually seems to have grown out of this phase. Lately, he has started up again... this time with avengence. In a 30 minute period being unattended, he chew completely threw the leg of a chair, took a chunk out of the side of a table and almost chewed threw the leg of a desk. I dont know what to do to make him stop. He is such a loyal dog otherwise. I am to the point where I might need to get rid of him or risk having no furniture left. This is my last hope. When I catch him chewing I yell "no" and he stops. As soon as I walk away he starts back up. It almost seems as if he is chewing out of spite.
