I was bitten by an unvaccinated dog 9 days ago on the leg which drew blood. the dog appears healthy now. do i need vaccine?

Hard to say: Rabies is a locality based problem. Local health departments are often the best source of rabies information since they keep track of the states rabies surveillance. If rabies has not been active in your region it is less an issue than when they find it in raccoons,foxes & skunks. The health department often keeps the vaccine on hand. I would call them or the local ER & discuss the issue.

Yes: And specific immunoglobulins too, see your doctor soon for assessment, and keep an eye on the dog, best wishes
