When your dog gets sprayed by a skunk you need to give them an outdoor bath with baking soda hydrogen peroxide, vinegar and dish soap.
Mix 1 quart hydrogen peroxide, ΒΌ cup baking soda, and 1 teaspoon dish-washing liquid into some bath water in a tub outside and then put your dog into the tub.
Then pour that mixture over the dog a few times and use some gloves and scrub the dog with it making sure to get it all over their fur coat and into their skin.
Then rinse them off with the hose and repeat as needed until the skunk smell goes away from your dog.
It may take you a few times of giving the dog a bath in this mixture before the skunk smell fully goes away.
