I'm a new home owner with a puppy... who took it upon herself to try to dig through a wall in her room. I have researched it ad nauseum, but I don't know what type of wall this is. It was constructed, as far as I can tell, in the past 20 years. The best I can guess is that it's drywall with some sort of insulation? Or is it just drywall and she didn't manage to puncture it? The claw marks from her nails are about 1 inch deep. Any help? Thanks!
