Thank you for your query,
As they are stray dogs, there are high chances of having rabies virus
So you have to complete the full schedule of 5 doses of antirabies vaccination
on 0, 3, 7, 14, and 28 days.
And one thing it is not possible to observe the stray dog for the first 10 days from the bite, you complete the 5 doses of antirabies vaccination.
The available antirabies vaccines are very safe and there are no side effects in comparision to the old injections.
So consult your Physician and take vaccination as per the schedule.
Hope I have answered your query.
