How can I effectively remove dog urine out of a rug?

To effectively remove dog urine from a rug, 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 apply it to 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 until the odor is gone.
