You have to take bleach put it on the floor to soak it up and put baking soda
Are you asking how to demo a wall and floor or do you want to refinish them?
Hello Kathy! If you have any pictures of the damage done by the dog it would be helpful. You can repair or replace a wall and flooring but you will get better suggestions if we can see the damage. Replacing drywall is an option. Repairing/redoing your floor is an option if we know what kind of flooring you have. It could be an easy fix or one that is more labor intensive.
Hi Cathy, sounds as though you're ready to rip it all up, tear it out, and throw it all away. Guess that's how to get rid of it. Bad dog!
I would call a carpenter in to repair the wall and the floor, most likely a 1 day job. I would research anxious dogs or dog separation issues for a happier dog. Good luck
