If you are bitten by a dog and there is no bleeding, you need to immediately rinse the bitten area with soapy water and physiological saline for ten to fifteen minutes, and then wipe it with iodine or alcohol for disinfection. If the dog has been vaccinated against rabies on time, it will generally be fine. If the dog has not been vaccinated against rabies and feels pain when wiping the wound, it is best to go to the hospital to get the rabies vaccine.
