My pup has sensitive skin. I've tried a number of shampoos marketed for "puppies with sensitive skin". None of them helped, many made it worse. Then I came across Wash Bar and after reading the very limited list of ingredients (all natural!) decided to give it a try. It's AMAZING! I couldn't believe what a rich nourishing lather it produced so quickly and rinsed away so cleanly. Her red irritated skin was normal after 2 uses and the itching stopped right away. Love this stuff.
