Hemorrhage on the inside of the dog's scratched lip is a single or multiple penetrating skin bites or scratches ("penetrating" means that at least the dermis and blood vessels have been injured, and the clinical manifestations are visible bleeding), which belongs to Class III exposure.

Generally speaking, for those with low immune function after Class III exposure and Class II exposure, passive immune agents (i.e. immunoglobulin) should be infiltrated around the wound at the same time of vaccination. If it is not used in time, the injection will still be effective within 7 days, and there is no need for injection after 7 days. You have head and face injuries, so you should take more preventive measures.
