Keep in mind, unless you correct them "in the act" they really have no clue that they have done something wrong, or more to the point "what they did wrong"…. shredding is pretty natural to a Basenji
Usually we put presents under the tree, but I just don't dare since getting the B girls! Presents all hide in closets until it's actually time for them to be opened. We always wrap special treats for the girls and the cat as well, so they can tear something open to get to the goodies. Then the treats keep them busy while everyone else is unwrapping. The great-grandkids have been warned NOT to leave their stuff on the floor or where they look like dog toys on tables, etc.
