Maintaining a clean coat between baths is highly desirable, especially for dogs with oily coats that are prone to collecting dirt. A number of household products have been used successfully as dry shampoos. Calcium carbonate, unscented talcum or baby powder, and cornstarch are all effective. They can be used frequently without damaging the coat or skin.
Work the substance into the coat and leave it in for 20 minutes to absorb oils. Then remove the powder with a soft bristle brush. If you’re showing your dog, remember that all traces of powder must be removed from the coat before entering the conformation ring for judging.
Commercial waterless shampoos (they require no rinsing) are sprays for quick cleaning problem spots. When used as an all-over spray, they are an excellent bath substitute. Apply and towel off.
