I know is very annoying for you, but I had to laugh when I read your posting. My first Golden, Natasha the Red Menace, used to have a thing for pillows also. Her trick was to exchange the ones from upstairs to the ones in the living room. She would run up and down the stairs exchanging pillows like an interior decorator.
She outgrew that as she got older. Since your Golden is 6 already, the only hope for getting him to understand that his behavior is not acceptable is training. Or, if you can live with bare couches for a while, perhaps he will forget about the pillows. Try to get him interested in some other kind of toys or chewees. Please, try, if you can, to avoid medication. We, as humans, are too used to solve all our problems by popping down pills. What our furry friends need is discipline
Good luck and let us know how he's doing. What is his name?
It might help if you try to find some answers from the American Dog Trainers Network at: http://www.canine.org/
