How can I effectively remove dog urine from carpet?

To effectively remove dog urine from carpet, start by blotting up as much urine as possible with paper towels. Then, mix a solution of equal parts water and white vinegar and apply it to the affected area. Let it sit for a few minutes before blotting it up again. Finally, sprinkle baking soda over the area, let it sit for a few hours, and then vacuum it up. Repeat these steps if necessary.
