Among the more common ones listed by several "Breed Sites" is this:

1 quart 3% Hydrogen Peroxide
1/4 cup Baking Soda
1 teaspoon liquid soap
(Dawn Dishwashing Detergent is often recommended, but any dish soap will work)

Mix in a bucket or bowl; it will be fizzy, a clue that you shouldn't try to mix it or store it in a bottle or other closed container. Thoroughly wet your dog with the solution. Knead it well into his coat, to chemically alter every bit of the thiols on his hair. Be careful to keep the formula out if the dog's eyes, nose and mouth; you can use a sponge to carefully wipe it onto his face. Follow the bath with a thorough rinse.

There are also a couple of products out there which do a fine job:

SOS

And this one I have used several times, and was effective...NilOdor Shampoo

You may wind up with some combination. Just like us, dogs have different oils in their skin and hair types that means rarely is there ONE answer.
