Dog eating couch pillows

[doogie]

Hi... I'm back again with another question. My 11 month old Golden Retriever was doing so well... I even had given her crate to the next door neighbors to use... but then, all of the sudden, she started taking the cushions and pillows right off the couch and began to distroy them!!! She had NEVER done anything like this before. Sometimes I would even catch her in the middle of the room with the pillow in her mouth... I'd say NO! and she would know it was wrong... he ears would go completely flat... she would submissive pee... but the minute I turn my back she would do it again! I DON'T UNDERSTAND! She knows its wrong and still does it??? So, I had to get the crate back and put her in there when I can't watch her... she is soooo sad when I put her back in the crate... she looks like I'm leading her to the fire when I tell her to get in her crate. So, I went out and bought a product that is supposed to stop puppies from chewing... you spray it on whatever the puppy is chewing and it is supposed to taste horrible to the dog... I sprayed it on all the couches.... SHE LOVES IT! I came down the stairs to find her laying on the couch - licking the product... I can't win! Any ideas?
