Dogs have a wonderful sense of smell, so it is important to remove the urine smell completely or your dog is likely to go again. As soon as you can, pour a solution of white vinegar and water on the spot where your dog has urinated, then use a wet vac to suck up the water or blot it as best you can with towels. Let it dry completely. If an odour remains, you can use other products to neutralise the odour completely. Baking soda and hydrogen peroxide can work, but a product that uses enzymes to completely break down the remaining urine will work best.
