Dog Bite Management - What You Need to Do Now
What the wounds show
Looking at your photos, the injuries are:
- Upper arm/thigh area: Multiple parallel linear scratches/abrasions (superficial, epidermal, some dried blood)
- Lower wound: A small puncture/shallow laceration with active minor bleeding
- Forearm: Several small superficial scratch marks and minor abrasions
These are Category II wounds (minor bites/scratches breaking the skin with minor bleeding) - they require medical attention even if the dog is vaccinated.
Step-by-Step Actions
1. Immediate First Aid (Do RIGHT NOW)
- Wash all wounds thoroughly with soap and running water for at least 15 minutes - this is the most important step and can reduce rabies virus transmission by up to 90%
- After washing, apply a povidone-iodine (Betadine) solution or 70% alcohol/ethanol to irrigate the wounds
- Apply gentle pressure with a clean cloth to stop the bleeding from the puncture wound
- Do NOT close the wounds with tape or bandages tightly - minor dog bite wounds should be left open or loosely covered to reduce infection risk
- Apply a thin layer of antibiotic ointment (e.g., mupirocin or bacitracin) and cover lightly
2. Go to a Doctor/Hospital TODAY
Even though the dog is vaccinated, you must see a doctor because:
- The doctor will assess the WHO/CDC exposure category and decide if rabies PEP is needed
- You may need a tetanus booster if your last one was more than 5 years ago
- Antibiotics may be prescribed (Ampicillin-clavulanate/Augmentin is first-line for dog bite wounds at higher risk)
Regarding Rabies - Vaccinated Dog Situation
This is the most common question. Here's what the guidelines say:
| Dog's Vaccination Status | What it means for you |
|---|---|
| Dog is fully vaccinated and healthy | Lower risk - but PEP decision depends on local public health rules and observation of the dog |
| Dog can be observed for 10 days | If the dog stays healthy for 10 days, rabies PEP can often be withheld or stopped |
| Dog vaccination status is uncertain | Start PEP immediately - do not wait |
Key point: Even if the dog is vaccinated, because the skin was broken and there was bleeding, most guidelines (WHO, CDC) classify this as a Category II exposure requiring at minimum rabies vaccination (without rabies immunoglobulin/HRIG). The dog must be observed for 10 days.
If You Have NEVER had a Rabies Vaccine Before:
- 4 doses of rabies vaccine: Days 0, 3, 7, and 14 (intramuscular, deltoid)
- HRIG (Human Rabies Immune Globulin): 20 IU/kg, injected around the wounds on Day 0
- Do NOT give HRIG and vaccine in the same syringe
If You Have PREVIOUSLY been vaccinated against Rabies:
- Only 2 doses of vaccine needed (Days 0 and 3)
- No HRIG required

Antibiotic Prophylaxis
Dog bites have a less than 5% infection rate when properly irrigated. However, for deeper puncture wounds like yours, a short course of antibiotics is usually prescribed:
- First choice: Amoxicillin-clavulanate (Augmentin) 875/125 mg twice daily for 3-5 days
- If penicillin-allergic: Doxycycline or a fluoroquinolone + metronidazole combination
Watch for These Warning Signs (Seek Care Immediately if):
- Increasing redness, warmth, or swelling around the wound
- Pus or discharge from the wound
- Red streaks spreading from the wound (sign of spreading infection)
- Fever above 38°C (100.4°F)
- Increased pain after 48 hours
Summary Checklist
- Wash wounds with soap + water for 15 minutes - do immediately
- Apply Betadine/povidone-iodine
- Go to doctor/hospital today - do not delay
- Ask about tetanus booster status
- Ask about rabies PEP (doctor will assess based on dog's vaccination proof and 10-day observation)
- Ask about antibiotic prescription (Augmentin)
- Observe the dog for 10 days - if it remains healthy, you are likely safe from rabies
Important: Even a vaccinated dog's bite requires a medical evaluation because vaccine efficacy in dogs is not 100%, and tetanus/infection risks are independent of the dog's vaccination status. Do not skip seeing a doctor.
