Thank you for your query,
You start taking the anti rabies vaccine
now or as early as possible as it is safe and there is no treatment for rabies.
As the exact immunity status of the dog will be known by doing the antibody levels and the protection will be conferred after taking regular and full vaccine schedule.
Observe the dog for 10 days from the day of bite and if the dog is healthy you can discontinue the remaining two injections of vaccine after your doctor advise.
So consult your doctor for further management.
Hope i have answered your query.
