First of all, dog skin is different from human skin, so it is generally not recommended to use human products to bathe dogs. If you don’t have a dog-specific body wash, consider using a natural, non-irritating shampoo to wash your dog. Make sure the products you use don’t contain strong chemical ingredients that may irritate your dog’s skin. Additionally, if you want a more natural option, you might consider using vinegar water to bathe your dog. Add a cup of apple cider vinegar to the water, then pour the mixture over your dog's body and pat dry with a clean towel. Vinegar can help remove bacteria and impurities from the skin, but please note that vinegar should not come into contact with your dog's eyes or wounds.
Finally, if you often need to bathe your dog, it is recommended to buy some shower gel specially prepared for dogs to ensure The products you use are safe and will not harm your dog’s skin.
