After being bitten by a dog, it is best to rinse the wound immediately for ten to fifteen minutes. If the wound is broken, squeeze out the blood and rinse while squeezing. After squeezing it clean, apply iodine for disinfection and sterilization. If you are bitten by a dog that has not been vaccinated against rabies, it is best to go to the hospital to get vaccinated to avoid infection. Because the mortality rate of rabies is 100%, it is safer to get vaccinated.
