The dog is not chewing the cushions to get back at you or to spite you even if she is a husky 
A lot of dog training is prevention so if you know she chews cushions when she is left do not leave cushions lying around or put her in a room without cushions or crate her.
Chewing is a major stress reliever so more likely to be the reason or she was bored.
If my dogs were doing some brand new bad behaviour I would give another command eg touch (my dogs will touch my finger if I put my finger out to them) If they are down the garden and I call touch they will charge up to me and touch my finger) They always know that the reward for the correct behaviour will be fantastic so will have no problem at all leaving what they were doing to give me the correct behaviour.
So if the dogs stole the butter I would ask for a good behaviour they would drop the butter and willingly give me the good behaviour. I would then punish myself for being an idiot for leaving the butter out However the dogs would still know that the good behaviour and doing as they are asked is the best most fun thing in the world.
Example tonight took the pysco pup (dumped on my doorstep for being so aggressive) to agility when we got her she would lunge bark and go to attack any dog that she saw. I have been giving her alternative behaviour for which she is rewarded when she wants to lunge, bark and attack. In my case a look dog. She looks at the dog, looks at me and then gets a fantastic reward. Now we are at the stage where she can run with other dogs, compete at agility etc.
The dominance method would be to shout at her, alpha roll her, squirt water in her face etc all of which would just make her behaviour worse due to fear and stress. Positive training all the way.
There is no behaviour it can not change.
Another example I had staffi pups dumped on my doorstep (see the pattern here!) They are young only weeks old but they will all sit, go down, tuggy, and release, wee on command, come to their names and not when you call another puppies name, all through clicker training. That would just not be possible with dominance training
