How can I effectively remove dog urine out of 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 pour it over the affected area. Let it sit for a few minutes before blotting it up with more paper towels. Finally, sprinkle baking soda over the area and let it sit for a few hours before vacuuming it up. Repeat these steps if necessary.
