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.
Dogs are natural diggers. Not only does digging produce new smells, but it's a way for the dog to release energy--they don't just dig when they want to bury a bone. One place dogs will dig if they can get away with it is in a flower garden. It takes months of care and maintenance to get a flower garden the way you want it. You should take active measures to protect it from being uprooted by man's best friend.
