If the puppy is not vaccinated and bites someone, there was a risk of rabies transmission. However, if the puppy remains healthy for 10-14 days after the bite, the risk of rabies transmission decreases. The incubation period of rabies is typically 2-3 months, but it can range from 9 days to 1 year or more. Post-Exposure Prophylaxis (PEP) which includes immediate wound cleaning, vaccination, and sometimes rabies immunoglobulin, is highly effective in preventing rabies if administered promptly after exposure. Your Situation Timing of Vaccination- You received your first vaccination 20 days after the bite. Ideally, PEP should be started immediately after the bite. Puppy's Health-Since the puppy is 2 months old and not vaccinated, it's essential to monitor its health closely. Recommendations Complete Vaccination Series- Ensure you complete the full vaccination series as recommended by  doctor. Monitor Puppy's Health-  Keep a close eye on the puppy's health. If it shows any signs of illness or abnormal behavior, seek veterinary advice immediately. Precautions Wound Care- Ensure the wound is cleaned and cared for properly to prevent infection. Avoid Further Exposure-  Avoid further exposure to the puppy until it has been vaccinated and cleared by a veterinarian.
