Hi, and sorry you were bitten by a dog. We are not doctors on these sites but I can give you some advice. I guess you don't know where the person with the dog lives right? If you did you could call animal control and they might have a record of who the dog is and what their vaccination schedule is. Or you can report the incident to them or to the police and give a description of the dog. Then, they could quarantine the dog. But if you have no idea where they live or the description of the dog doesn't help that you give to animal control then I guess you should see a doctor right away for vaccination shots against rabies.
