Top breeders and professional groomers worldwide recommend So-Dirty Shampoo, a deep cleansing dog shampoo designed for the dirtiest and smelliest parts of owning a dog. It works to a rich foam, but leaves no residue and allows for a quicker rinse time. The best part is that So-Dirty Shampoo does not strip your pup's natural oils from their skin or coat and is free of parabens, silicones, and artificial thickeners. It is also safe for puppies, kittens, the environment, and can be safely used with topical flea and tick treatments.
