How long a dog bite can live without shots is the first thing to determine if rabies will be contracted. If infected with rabies virus, the patient will most often die within 3-6 days, but there are cases where the disease develops 1-3 months, or even more than 3 months, after the bite. If not infected with rabies virus, there is no effect on life. Current research proves that the incubation period of rabies is 3 months to 1 year, which is related to the number of viruses, the depth of the wound, and its own defense mechanism, but most clinical cases of rabies virus infection develop within 3-6 days and die of respiratory or circulatory failure. If the injured dog can exclude having rabies, or if the patient is bitten but the mucous membrane is not broken, the risk of rabies virus infection is low. Patients may not be infected with rabies virus without an injection, and there is generally no impact on life. However, patients are advised to visit the CDC or a specialty hospital promptly after a dog bite to dispose of the wound and get vaccinated as soon as possible. For those who have been bitten for several months or years and the health status of the injured dog is unknown and has not been disposed of, rabies vaccination should also be administered according to the procedure.
