Frequent water treatments are highly undesirable, although it is difficult for Norwich Terrier owners to adhere to this recommendation. Dogs do not hesitate to dig in the ground or actively explore the surroundings, so the coat gets dirty regularly. Bathe your pet only as a last resort so as not to disturb the natural fat balance of the skin. To remove surface dirt, use a dry shampoo by rubbing it into the dog’s coat and brushing out thoroughly.
