It would be best if you could get your dog seen in person by a vet as soon as possible, so her wound can be evaluated and she can get a rabies booster shot. She should have some protection from her vaccination when she was a year old, but it's important to keep up with the boosters, on the schedule your vet recommends.
Cleaning the wound with hydrogen peroxide or betadine scrub to disinfect it and then applying the plain Neosporin is good first aid until you can get her to the vet.
If the wound is not actively bleeding, that's good, but if it is bleeding and you can't stop it by applying pressure, you need to have her seen as soon as possible.
You've done everything you can do at home, so bring your dog to the nearest ER vet center, if your vet doesn't have emergency hours and it is now after hours for you.
I hope all will be well with your furry girl!
