Thank you for your question.
I am Dr Saha, I shall try my best to help you.
I am sorry for your suffering.
It is likely that you would need antibiotic orally.
It will need an examination by your doctor & prescription.
Exact antibiotic can be decided after examination only.
Usually it is from penicillin group like amoxicillin-clavulanate or cephalosporin group like keflex.
Antibiotic can be needed for a week or more depending on the type of wound contamination.
You can continue antibiotic cream like neosporin.
You can take antiinflammatory analgesics like motrin or naproxen, if there is no other contraindication.
Warm application can be soothing.
Please keep the leg elevated whenever possible.
You would not likely need vaccine as it was not a stray dog.
Still, you need to get it confirmed.
I hope this information helps.
If there’s anything else I can do, please let me know.
If you are satisfied, please rate my answer as good or excellent.
