Tomato juice is the old school way to remove the smell. My 100lb shepherd got it a couple of years ago. Fortunately I was ready with this concoction:
Skunk Stink Removal Recipe
In a plastic bucket (not metal), mix the following ingredients thoroughly:
1 quart of 3% Hydrogen Peroxide
1/4 cup of baking soda
1 tablespoon of liquid dishwashing soap (Ivory is recommended)
For very large pets you can double the recipe (recommended) or you can add one quart of lukewarm tap water to provide complete coverage.
Wash your dog thoroughly, working the solution deep into the fur. Make sure you really saturate the areas where she took the direct hits. Your nose knows.
Skunks usually aim for the face, but try to keep the solution out of her eyes, as it can sting. Keeping a bottle of pure water nearby to rinse the eyes is a good idea.
Leave the solution on for at least 5 minutes or until the odor is gone. You may need to rinse and repeat with some of the more stinky areas.
After you’re done, thoroughly rinse your pet with lukewarm water.

The above worked great, I took the pooch to one of those dog washes (built into a car wash) and had him pretty stink free by the time I got home.
I keep the ingredients at the ready both at home and the cabin. Fortunately with 3 dogs I've only had 1 time I needed it. But its probably only a matter of time before I need it again.
