Fox Terrier(?) chews up EVERYTHING?

Well, there are many ways to stop these actions. You could stop her from getting on the couches/furniture. Pick up any kind of foam , some foam can swell in a dogs tummy and may cause serious illness and even death. You can try the pet spray sold at Wal-Mart which should stop pets from getting on furniture. As far as blankets and whatever you can give her just one blanket that is hers to do whatever too and the rest reprimand her for getting on or messing up. Also what kind of dog food is she eating? Believe it or not some of the cheap dog foods can leave a dog without nutrients and therefor leave their bellies feeling hungry. The better dog foods in the $20 to $40 for 25 lb bags should be better for her. If the problem continues you may consider pet behavior cles at a shelter. Trust me the ones in pet stores aren't always helpful. Remember all dogs are pack animals and if a specific leader isn't established they'll never respect you or your home. Good luck!
