The owner of the pit bulll is responsible for the damages caused by their dog, and they've violated the leash law. If you know who owns the pit bull, you can send your medical bills to them, and if they won't pay them, sue in Small Claims court.
It's also possible that they may have homeowner's insurance that covers the damages done by their dog, although some carriers don't cover pit bulls.

The previous answer is totally correct. They are responsible for the bills incurred to treat your dog. You cannot get damages for pain and suffering. Small Claims Court is probably your best bet unless the medical bills exceed $7,500. If so you will have to file in Superior Court.
I agree with the other contributors. I would also add that you can complain to animal control, and seek to have the dog quarantined, and go to "dog court" if you feel strongly enough about this.

I agree with my colleagues; however, you will have to prove that "this" dog was the one that attacked you. If you have not done so already, you should file a police report and/or a report with animal control.
