She just a baby and will no doubt be teething and chewing is part of a puppy's life and is really too young to properly teach not to destroy an expensive bed. I would buy her a cheap bed until her brain is more developed and she's not overly intimidated by your attitude when seeing the destruction to the expensive bed.
She'll do better during these early weeks if things that attract her to chew are kept away from her over trying to constantly discourage her or keep spraying the bed with things as the impulse to chew the bed is likely quite strong. Once she's a little older and has learned more impulse control from your training her, you can re-introduce her to the bed a little as a time until you are sure she's not going to chew it. After training her and she's older, a simple "No" will keep her from chewing but I would not leave her alone with the bed until she's well over a year or more, fully trained and well-behaved and well past her chewing phase. But 11 weeks is just an infant and she's going to be destructive for quite a while if she has access to things.
