Dogs routinely dig for several reasons, all of which can be seen as instinctual behaviors that they got from their ancestors. One reason your dog may be digging into the couch is due to how dogs would dig out dens in the wild as a place to rest and protect themselves from various predators. Another reason may be due to your dog wanting to conceal the place where they sleep, like animals do in the wild.
Dog's hiding may hide medical problem. Jodi has a 12-year-old female dachshund named Phoebe who lived in the house until a few years ago. The family changed her into an outside dog when she began hiding under beds for hours at a time. They found the behavior frustrating, but tolerable. When they got a cat, the behavior worsened. Now, if she can sneak in the house, she will hide behind the couch or under a bed, sometimes for 24 hours or more.
