Dog Bite Management

Immediate Wound Care

All dog bite wounds require immediate copious irrigation with sterile normal saline or dilute povidone-iodine solution, followed by careful debridement of devitalized tissue, as recommended by the Centers for Disease Control and Prevention, to prevent infection and reduce rabies risk 1, 2, 3
Gentle irrigation is critical; avoid high-pressure irrigation as it may force bacteria deeper into tissue planes, according to the World Journal of Emergency Surgery 2, 3
Explore wounds for tendon or nerve laceration, bone involvement, and foreign bodies, as suggested by the Infectious Diseases Society of America 4, 5
Avoid suturing most wounds when possible, as closure increases infection risk, as recommended by the Centers for Disease Control and Prevention 1, 2

Preemptive antibiotic therapy for 3-5 days is indicated for high-risk wounds, including hand, foot, face, or genital locations, deep wounds, wounds near joints or bones, puncture wounds, immunocompromised patients, asplenic patients, those with advanced liver disease, or wounds with significant edema, as recommended by the World Journal of Emergency Surgery 2, 3, 4, 5
Amoxicillin-clavulanate is the preferred agent, providing coverage against Pasteurella multocida, Staphylococcus, Streptococcus, and anaerobes, as suggested by the Infectious Diseases Society of America 4, 5, 6
Doxycycline 100 mg twice daily is an alternative oral option, with excellent Pasteurella coverage, as recommended by the Infectious Diseases Society of America 4, 5, 6

Administer tetanus toxoid if not vaccinated within the past 5-10 years, as recommended by the Centers for Disease Control and Prevention 1, 5, 6
Tdap is preferred over Td if the patient has not previously received pertussis vaccination, as suggested by the Centers for Disease Control and Prevention 5

Consult local health officials immediately to determine if rabies post-exposure prophylaxis is needed, as recommended by the Centers for Disease Control and Prevention 1, 5, 6
If indicated, administer both rabies immunoglobulin and vaccine on days 0, 3, 7, and 14 for previously unvaccinated individuals, as recommended by the Centers for Disease Control and Prevention 1, 5, 6

All patients must be evaluated within 48-72 hours to assess for infection signs, as recommended by the Praxis Medical Insights 5
Hand wounds require particularly close monitoring due to higher complication rates, as suggested by the Infectious Diseases Society of America 4, 5
Elevate injured extremities to reduce swelling and accelerate healing, as recommended by the Infectious Diseases Society of America 4, 5

Hand wounds have the highest infection risk and may require 4-6 weeks of antibiotics if complications develop, as suggested by the Infectious Diseases Society of America 4, 5
Deep wounds near joints or bones require evaluation for septic arthritis or osteomyelitis, as recommended by the Infectious Diseases Society of America 4, 5
Immunocompromised, asplenic, or patients with advanced liver disease are at risk for Capnocytophaga canimorsus sepsis and require immediate broad-spectrum antibiotics, as recommended by the World Journal of Emergency Surgery and the Infectious Diseases Society of America 2, 4, 5

Cellulitis, abscess formation, septic arthritis, osteomyelitis, tendonitis, and rarely bacteremia are common infectious complications, as reported by the Infectious Diseases Society of America 4, 5
Dog bite wounds yield an average of 5 bacterial species, with 60% containing mixed aerobic and anaerobic organisms, as reported by the Infectious Diseases Society of America 4
Pain disproportionate to injury severity suggests periosteal penetration or deep infection, as suggested by the Infectious Diseases Society of America 4
