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)
Rubber or latex gloves
Mix in an open container (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 warm water and then the solution while it is still bubbling. Knead it well into his coat, to chemically alter every bit of the oils 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. Let the solution stand for 10 minutes before rinsing. Follow the bath with a thorough rinse. Be sure to protect the eyes when rinsing the head. Chances are you will not get all of the smell off of the face and will have to live with that as it wears off. You can try Tricotine Liquid Douche Concentrate or any over-the-counter douche.After bathing, check your dog's eyes. If they are red and watering, your dog may have taken a direct hit in the face. Skunk spray won't blind the dog, but it's very painful. Contact a vet.
