We have a wonderful dog as well, but she can not be trusted alone. If left alone with access to trash she will scatter it throughout the house, then when you return she will bolt out of the door when you open it because she KNOWS she did something wrong. Just couldn't help it. I had a Golden/lab mix and it was an absolute destroyer of anything cotton filled, or any bedding. I'd buy a nice bed for her only to come home to a yard full of ghetto snow.

In other words, dogs are dogs. They lack impulse control, despite being otherwise well trained. What is needed here is human training. Don't give the dog the opportunity to destroy these things. Crate train, keep the dog locked away from the laundry and the furniture, only give non-destructible toys etc. The dog's behavior isn't changing, time to change yours.

Also, don't play with your hands. use toys, not your hands when playing. Hands are for petting and feeding, not playing if you don't want to get bit.
