Here are 2 beautiful examples of my puppy's handiwork.
This one is in the gated area that they stay in all day. Plenty of toys, plenty of room to move - they attacked the defenseless wall. (Notice they stopped when they hit the stud? You can see the nail in the stud.)
This one (aslso in the same gated area) they started, must've gotten bored and decided to leave it alone. It's been there several weeks in this same state.
I was waiting to see if they would continue damaging the walls, but alas - they seem to have stopped. We will now attempt to repair the damage. (Notice I said 'attempt'....)
