Is your dog vaccinated against rabies? The vaccine is highly effective. The chances of a vaccinated dog being able to infect rabies is very very low. If you are still concerned, ask about preventative shots for yourself or ask about a titer for the dog (a titer is a test that checks the immune response of an animal to a vaccine, basically it can tell if the vaccine "took" or not). In the US, no one really is going to worry about getting nipped or scratched by the teeth of a pet dog if the dog has been vaccinated for rabies at the usual 4 months of age or so.
If she is not vaccinated against rabies, then you should talk to a doctor as soon as possible since I am guessing rabies are high-risk in your area from stray dogs.
