If your dog has strong oil secretion and needs to improve its diet, try to choose light food instead of spicy food. Don’t choose dog food that is too oily. Let your dog drink more water and eat more vegetables and fruits every two days. Give your dog a bath once a week. Excessive oil secretion in dogs may cause folliculitis and aggravate body odor, so it must be treated and corrected in time to avoid aggravation of the situation.
