How many hours should the dog bite last?

The dog bite should not last longer than 48 hours. If the dog bite lasts for more than 48 hours, the dose of the first injection must be doubled. Regardless of whether you are bitten or scratched by a dog, whether there is bleeding or not, as long as the skin and mucous membranes are damaged, the rabies vaccine should be injected as soon as possible. During the vaccination period, avoid alcohol, strong tea, spicy food, and strenuous exercise.
