"Chewing: Punishment after the fact
should be avoided. When a dog is punished after the behavior has
occurred, it only confuses your dog.
If you come home and see that your TV
remote has been chewed and then you punish your dog, your dog will
associate the punishment with your homecoming.
The next time you leave the house, your
dog will become anxious. To relieve the anxiety, your dog will chew.
You come home, find the chewed up item
and punish your dog. It can become a vicious cycle."
