How can I effectively remove dog urine from a carpet pad?

To effectively remove dog urine from a carpet pad, start by blotting up as much of the urine as possible with paper towels. Then, mix a solution of equal parts water and white vinegar and pour it over the affected area. Let it sit for a few minutes before blotting it up with more paper towels. Repeat this process until the odor is gone. Finally, sprinkle baking soda over the area and let it sit overnight before vacuuming it up the next day.
