Thanks for writing to HCM.
Yes,you need immunization
with anti-rabies vaccine
and tetanus toxoid injection
Though the risk of rabies infection is very less in this case but rabies is a deadly infection once someone gets it mortality is 100%. Also immunity to rabies starts after 7 days of first dose hence it will late to observe for 10 days.Hence it is better to go for immunization.
Hence visit to the doctor for immunization and observe the dog for 10 days for symptoms of rabies.
You will require total 5 injections of anti-rabies vaccine on day 0,3,7,14 and 30 and one T.T. injection if you have not received booster dose in last 5-10 years.
Get your dog immunized for rabies with repeat doses to be given annually.
Though there will be controversies in vaccination
in this case but i would prefer to go for vaccination as it comes category 2 of dog bite.
Hope this could help you.
