Management of Dog Bite Wounds
Initial Management
- Dog bites should be cleaned immediately with copious irrigation using water or normal saline solution to significantly decrease the risk of bacterial infection 1
Suturing Decision Algorithm
Facial Wounds
- Facial wounds can be closed primarily after copious irrigation, careful debridement, and administration of preventive antibiotics 1
Non-Facial Wounds
- Primary closure of dog bite wounds in areas other than the face is generally not recommended 1
- For non-facial wounds, consider approximating edges without complete closure 1
- For non-facial wounds, especially hand wounds, consider leaving wounds open due to a higher risk of infection if closed 1
Antibiotic Prophylaxis
- Early preventive antimicrobial therapy (3-5 days) is recommended for immunocompromised patients, asplenic patients, patients with advanced liver disease, wounds with pre-existing or resulting edema, and moderate to severe lesions, especially on the hand or face 1
- Amoxicillin-clavulanate is the first-line prophylactic antibiotic as it is active against both aerobic and anaerobic bacteria commonly found in dog bite wounds 1
Additional Considerations
- Tetanus prophylaxis should be administered to patients who have not been vaccinated in the last 10 years (or 5 years for dirty wounds) 1
- The Tdap vaccine is preferred over the Td vaccine if the former has not been previously administered 1
- Rabies prophylaxis may be necessary - consult local health authorities to determine if vaccination should be initiated 1
- A healthy dog that bites a person should be confined and observed daily for 10 days; any illness should be reported immediately to the local health department 2, 3
Special Considerations
- Hand wounds have a particularly high risk of infection and should generally not be sutured 1
