Scrape the dog's teeth to see if there is bleeding. First wash the wound with soap and water for more than ten minutes. If bleeding occurs, squeeze out the blood, then apply iodophor for disinfection. Finally, go to the hospital for a rabies vaccine as soon as possible. Avoid contracting rabies. If there is no bleeding, it will be fine. You don't need to give an injection. Just rinse and disinfect the bitten area.
