As soon as you wash her, have her give your Chihuahua a proper bath, you'll first need to. Wash baby's hair with the Epsom salt shampoo again immediately afterward. It was fantastic even on her super long and thick and is often compared to a pre-Raphaelite painting, which I'll take. Lather the shampoo into their fur coat using either your hands or a wash cloth. It's true though, in five years I didn't have to.
