A concise and straightforward answer to this question is NO. Dry dog shampoo does not hurt your dog. There could be a few scenarios where the shampoo for your dog could be problematic. Suppose your dog is facing skin or eye infections. In that case, your dog’s skin is too sensitive; your dog licks and ingests shampoo during bath time. There is a possibility that the shampoo will result in nothing short of distress and agony for both of you. Otherwise, if you are using the shampoo carefully, it will help you care for your dog without any great hassle. Get your dog cleaned and scented within a few minutes.
