Welcome to HCM.
There are 2 different consideration as far as infectious disease is concerned in your case.
1. Rabies: If the dog is fully vaccinated, no need to worry. otherwise you have to take Rabies vaccine
as soon as possible.
2. Tetanus: If it is more than 10 years, you need an Inj. TT, also as early as possible.
Both of these diseases are reported to have a very bad consequences. So don't delay.
All the best
