Rub your dog briskly with a towel to begin the drying process. If you have a forced air dryer, that would work well to help dry them faster. Keep your dog in a warm area to dry. Give him a towel to lay on to help wick water from his under coat. If you chose to use a human hair dryer, be very careful to not overheat your pet, and keep the hair dryer well away from him to prevent burns.
If your dog got any of the skunk smell on his collar, leash, your clothing, or anything else that can go into the washing machine, you can remove the smell by adding a half cup of baking soda to your regular laundry detergent.
If any of these options are impossible for you, contact a local groomer. Many of them will have special rates and be available for last minute ‘de-skunking’ appointments. If it is necessary to put your dog in the car while he is still skunked, put down plastic tarps or lots of towels to keep the spray from contaminating your car.
