Can dogs use human shampoo? No, because the skin structures of people and dogs are different, human shampoo is harmful to dogs.
Dogs cannot use human shampoo, because the shampoo used by humans is too acidic for dogs, which will cause dry skin to cause damage to the dog's own skin immunity, causing skin diseases, etc. Therefore, you must use a shampoo for dogs so that you do not harm the dog's skin.
Dogs should not bathe too frequently because they rely on the hairs of the whole body to protect them. The secretion of oil from the sebaceous glands can form a protective film to prevent the invasion of foreign pathogens. Excessive bathing will destroy this protective film. Therefore, dogs should not take excessive bathing, especially washing every day will especially harm the dog's skin. It is recommended to wash it once every fifteen days in winter and once a week in summer.
