You must have taken the last dose of rabies vaccine
about a month ago. I think you just have to watch the dog if possible for aggressive behavior, tendency to bite without being provoked, lethargy, paralysis
of saliva from its mouth during next 10-15 days. In case these symptoms are visible, you may take an injection of anti-rabies hyper- immune globulin
followed by one more shot of rabies vaccine to protect you.
Best of luck.
