Many traditional shampoos are more suitable for washing dishes than for cleaning your dog's sensitive skin. They are not pH neutral and are not microbiome gentle. They strip away the natural protective lipid layer of the dog’s skin and remove its natural defense against pathogens.
For the best results for both dog health and coat appearance, it is best to select a pH balanced and microbiome gentle shampoo. This is especially important in dogs who are routinely bathed more than once a month.
