Animal Bite in a Child: What to Do

Immediate first aid for a bite

The first priority is wound care, which significantly reduces infection risk:

1. Control bleeding — apply firm direct pressure with a clean cloth 2. Wash the wound thoroughly — rinse under running water for at least 5–10 minutes; soap and water is appropriate. Thorough wound cleansing is the single most important infection-prevention step and also reduces rabies transmission risk 1Ref 1Centers for Disease Control and Prevention (2024).Rabies Post-exposure Prophylaxis Guidance.Rabies PEP regimen, wound cleaning as first step in rabies prevention, bat exposure evaluation for children 3. Do not close the wound yourself — tape, bandage strips, or glue should not be used to pull bite wound edges together at home; many bite wounds are intentionally left open or loosely closed by providers to reduce infection risk 4. Call the child's doctor or go to urgent care or the ER depending on wound severity — do not delay because the wound seems small; puncture wounds from cat or dog teeth can look minor on the surface while tracking bacteria deep into tissue 2Ref 2Centers for Disease Control and Prevention (2026).Zoonotic Exposures: Bites, Scratches, and Other Hazards.Animal bite wound care, polymicrobial infection risk, cat bite infection rate, antibiotic prophylaxis recommendations

Infection risk: dogs, cats, and other animals

Bite wounds have a higher infection rate than other lacerations because animal saliva contains numerous bacteria. Among common animals:

• Dog bites are the most common in children; wounds are often polymicrobial, harboring Pasteurella, streptococci, staphylococci, and anaerobic organisms. Deep puncture wounds carry higher infection risk than shallow lacerations 2Ref 2Centers for Disease Control and Prevention (2026).Zoonotic Exposures: Bites, Scratches, and Other Hazards.Animal bite wound care, polymicrobial infection risk, cat bite infection rate, antibiotic prophylaxis recommendations
• Cat bites carry a high infection rate despite often looking like small punctures — cat teeth are narrow and sharp and can push bacteria (Pasteurella multocida in particular) deep into tissue, including tendons and joints. Cat bites on the hand are prone to developing serious infection within 12–24 hours 2Ref 2Centers for Disease Control and Prevention (2026).Zoonotic Exposures: Bites, Scratches, and Other Hazards.Animal bite wound care, polymicrobial infection risk, cat bite infection rate, antibiotic prophylaxis recommendations
• Human bites also carry infection risk and should always be evaluated

Signs of bite wound infection include increasing redness, warmth, swelling beyond the immediate wound edge, pus, red streaking, swollen lymph nodes, or fever.

Rabies risk: which animals and what to do

Rabies is rare in domestic animals that are vaccinated, but risk assessment is a routine part of bite evaluation. Factors providers consider 1Ref 1Centers for Disease Control and Prevention (2024).Rabies Post-exposure Prophylaxis Guidance.Rabies PEP regimen, wound cleaning as first step in rabies prevention, bat exposure evaluation for children:

• Dog and cat bites from owned, vaccinated animals — lower risk; the animal is typically observed for ten days to confirm it does not develop signs of illness
• Bat exposure — bats are the most common source of rabies transmission in the US; a child who was in a room with a bat (even without a visible bite) may need evaluation because bat bites can be very small 1Ref 1Centers for Disease Control and Prevention (2024).Rabies Post-exposure Prophylaxis Guidance.Rabies PEP regimen, wound cleaning as first step in rabies prevention, bat exposure evaluation for children
• Wild animals — raccoons, skunks, foxes, and coyotes are higher-risk; a bite from these animals warrants immediate evaluation for post-exposure prophylaxis
• Small rodents (mice, squirrels, hamsters, guinea pigs) — considered very low risk for rabies transmission
• Stray or unvaccinated animals whose status is unknown — warrant evaluation

Rabies post-exposure prophylaxis (PEP) — which includes immune globulin and a four-dose vaccine series — is highly effective but must be started promptly 1Ref 1Centers for Disease Control and Prevention (2024).Rabies Post-exposure Prophylaxis Guidance.Rabies PEP regimen, wound cleaning as first step in rabies prevention, bat exposure evaluation for children. Public health departments can assist with risk assessment.

What evaluation and treatment may include

When a child is seen for an animal bite, the provider will:

• Assess the depth and location of the wound
• Review tetanus vaccination status and recommend a booster if needed 3Ref 3Centers for Disease Control and Prevention (2024).Clinical Guidance for Wound Management to Prevent Tetanus.Tetanus vaccination status review and booster consideration after bite wounds
• Assess rabies risk and consult public health if needed
• Decide on wound closure — many bite wounds, particularly punctures, are left open or loosely closed; facial wounds may be an exception due to better blood supply
• Consider prophylactic antibiotics, particularly for cat bites, bites on the hand, deep punctures, and bites in immunocompromised children — amoxicillin-clavulanate is the typical first-line choice 2Ref 2Centers for Disease Control and Prevention (2026).Zoonotic Exposures: Bites, Scratches, and Other Hazards.Animal bite wound care, polymicrobial infection risk, cat bite infection rate, antibiotic prophylaxis recommendations
• Advise on wound care and signs of infection to watch for at home

Children bitten on the face by a dog may need evaluation in an emergency department with surgical or plastic surgery consultation, because even wounds that seem cosmetically minor can involve deeper structures.
