                                                          Human shampoos are never good for pets. For fleas or other external parasites, use a medicated dog shampoo specific for those purpose. Use a flea treatment such as Advantage or Frontline will also remove and prevent external parasites. For internal parasite you must go to a veterinarian for de-wormers.
