Shampoo therapy is necessary for pets with dermatologic ailments. A pet's coat operates like a magnet for all types of dirt, dander, toxins, fungus, bacterias, and irritants. To receive the optimum benefit from therapeutic shampoos, topical contact time during the course of application is very important. Allowing the shampoo to sit on the skin allows it to get in the skin to provide soothing moisture. Another important step of using dog shampoos is rinsing because surfactants can produce skin irritation when they are not totally removed. Therapeutic shampoo will leave your dog' skin healthy, smooth, pliable, shiny, and manageable.
