Do I need an injection if the dog bites me if the skin is not broken but the skin is red?

1. The biting dog has regular vaccinations and deworming; the dog is in good health, has a normal spirit and appetite, and does not have any cold symptoms.
2. Rarely come into contact with other animals, and have not been hurt or licked by other animals recently.
3. There are reasons for being bitten, such as forceful pulling, teasing the dog to deliberately provoke it, snatching food, toys, etc., or accidental injury during play.
If the above conditions are met, no injection is required if bitten, indicating that the dog is healthy, and healthy dogs do not carry infectious rabies virus, so they are less likely to be transmitted to humans. Only dogs infected with rabies are contagious 3 days before and during the episode. If you are unsure about your dog's health and vaccine status, you should get a shot and follow a ten-day observation method.
