1. Generally, domestic dogs don't have rabies virus unless they go out to play and are scratched and bitten by dogs with viruses.
2. Rabies virus will not attack within 24 hours. It is recorded that someone was bitten by a mad dog, and the position of his face. That was three days before the attack.
If you are really worried, it will be fine to get vaccinated tomorrow. Just in time.
Let's assume that your brother's dog has rabies, and it is paroxysmal and contagious.
First, you are defeated.
Second, the part is in the hand, away from the brain.
Third, if it happens, it will be at least half a month later.
In addition, rabies vaccine needs a third injection to produce antibodies in the body.
Absolutely timely.
