Since you already completed a full post-exposure vaccination course with the Rabies Vaccine in September 2024, you still have immunological memory protection.
In such cases, if another bite occurs later, you usually do not need the full course again. Instead, only 2 booster doses (Day 0 and Day 3) are recommended as per rabies post-exposure guidelines.
In your situation, the risk is very low because:
• The dog is a 4-month-old indoor pet.
• It already received one rabies vaccination.
• It has no contact with street or stray animals.
If the bite is very minor (no bleeding or just superficial scratch) and the dog remains healthy for the next 10 days, vaccination may not be necessary. However, if there was bleeding or a deeper bite, it is safer to take 2 booster doses.
Next Steps
• Immediately wash the wound thoroughly with soap and running water for at least 15 minutes.
• Apply an antiseptic like povidone-iodine.
• Observe the dog for 10 days. If the dog stays healthy and active, rabies risk is extremely low.
• If the wound had bleeding or puncture marks, take 2 booster doses of rabies vaccine (Day 0 and Day 3).
• You do NOT need Rabies Immunoglobulin (RIG) because you were already vaccinated earlier.
Health Tips
• Always wash any animal bite immediately, even if it seems minor.
• Ensure your pet completes the full rabies vaccination schedule with annual boosters.
• Avoid provoking pets while playing, as sudden movements can trigger defensive bites.
If you want, you can book an online consultation and share a photo of the bite wound, and I can guide you on whether booster vaccination is actually needed in your case.
