Dog urine can bleach finish, darken wood, and leave odor in the joints. Clean residue first, neutralize odor, then repair finish or boards as needed.
Act while it is fresh
Blot liquids immediately. Enzyme cleaners designed for pet urine break down odor compounds better than perfume sprays. Keep the floor only damp—do not flood seams.
Finished vs raw wood
On intact polyurethane, clean and neutralize, then assess finish dulling. Where urine reached bare wood, expect darker tannin stains that may need oxalic acid (wood bleach) after sanding, used with full safety gear and manufacturer directions.
Odor in gaps
Seams and under-trim pockets hold smell. Clean what you can reach; severe cases may need board replacement if odor persists after enzyme treatment and drying.
Refinish path
Once dry and odor-free, screen and recoat light finish damage, or sand and refinish zones where color is permanently changed. Block future accidents with pads and prompt cleanup.
