Don't worry, this is a very common and completely solvable problem! The key to successfully cleaning dog urine from a couch is to tackle both the visible stain and the invisible, odor-causing bacteria deep within the cushions. With the right approach, you can restore your couch to its former glory.
Your first and most crucial step is to act quickly. Grab some paper towels or a clean, absorbent cloth and blot the wet spot firmly. The goal is to soak up as much of the urine as possible. It is essential that you blot, not rub or scrub. Rubbing can spread the stain and push the urine deeper into the fabric and cushion foam, making the odor much harder to remove later.
Once you have blotted the area thoroughly, you will need a specialized cleaner. While household soaps might seem like a good idea, they are not effective against the uric acid in dog urine, which is the source of that stubborn, lingering smell. You absolutely want to use an enzymatic cleaner specifically designed for pet stains. These cleaners contain enzymes that literally break down and digest the odor-causing acid and bacteria. Generously spray the enzymatic solution onto the affected area, ensuring you saturate it enough to reach as deep as the urine did.
Let the cleaner sit and work its magic for the amount of time recommended on the product's label, which could be anywhere from 15 minutes to several hours. This waiting period is critical for the enzymes to do their job. After it has sat, blot the area again with a new clean cloth to absorb the excess moisture. Finally, allow the spot to air dry completely. For any faint, lingering odor after it's dry, you can sprinkle the spot with baking soda, let it sit for a few hours, and then vacuum it up thoroughly. Following these steps will give you the best possible chance of completely eliminating the stain and the smell for good.
