Not to scare you as well but since they haven't located the dog I would get the rabies vaccine. In Texas it is common practice if the dog is not known to be vaccinated and not located to get the vaccine. Unfortunately I have seen from my vet friends it is unpleasant round of shots but the rabies virus is not one you can survive. In my area if they bite twice they are euthanized, it stinks but the owners obviously are not taking care of their responsibility and the dog is danger to to everyone.
