Kids and animals go together. Most of the time that is a wonderful thing. But animal bites happen, and when they do, the first few minutes of care matter more than most parents realize.

Dog bites are the most common, followed by cat bites. Both can cause more damage than they appear to on the surface, and cat bites in particular carry a high infection risk because of how deep and narrow those puncture wounds are.

This guide walks you through exactly what to do right after a bite, how to recognize signs of infection, and which situations need a doctor visit regardless of how minor the wound looks.

The Short Version: What to Do Right Now

If the bite just happened and you need the steps immediately, here they are. The full explanation for each step is further down.

Step 1: Control the Bleeding

Apply gentle but firm pressure using clean gauze or the cleanest cloth you have available. Hold the pressure steady. Do not keep lifting it to check, give it at least 10 minutes if you are going to check. Checking disrupts the clotting process just like it does with nosebleeds.

If blood soaks through, add more gauze on top rather than removing what is already there. For a bite on the hand or arm, elevating the limb above heart level while applying pressure helps slow the bleed.

Most bite wounds from household pets are not heavy bleeders. If you are dealing with a wound that will not stop with steady pressure, that is a 911 call. Our guide on what to do when a child's bleeding won't stop covers that situation in detail.

Step 2: Wash the Wound: This Is the Most Important Step

Thorough washing with soap and running water is the single most effective thing you can do to reduce infection risk from an animal bite. The goal is to flush bacteria out of the wound before it has a chance to take hold.

Use mild soap and run water over and through the wound for a full 15 minutes. I know 15 minutes feels like forever with an upset child. Set a timer anyway. This is what the CDC recommends for a bite that could carry rabies, and it is the one step that is entirely in your hands.

Do not pour hydrogen peroxide or full-strength iodine into the wound. Soap and running water is what parents should use at home. If this was a wild animal bite, your doctor may irrigate the wound with a diluted antiseptic solution, which is a different thing done by a clinician, not something to try at the kitchen sink.

Step 3: Cover the Wound

After washing, pat the area dry and cover it with a clean bandage or gauze pad. For a puncture wound, do not seal it tightly. Punctures need to be able to drain. A loose dressing over the top is appropriate.

For a laceration or tear, a clean bandage held in place with medical tape works fine as a temporary cover until you can get medical care. Do not attempt to close a bite wound yourself with tape or butterfly closures before a doctor has seen it. Closing a contaminated wound traps bacteria inside.

Step 4: Call Your Doctor

This step is NOT optional. All animal bites in children should be evaluated by a medical professional, even if the wound looks minor. Here is why:

• A doctor needs to assess infection risk and decide whether antibiotics are needed
• Tetanus vaccination status needs to be reviewed
• Rabies exposure needs to be assessed depending on the animal and circumstances
• Some wounds need professional cleaning or closure that cannot be done at home
• Bites to the hand or over a joint may involve deeper structures that are not visible on the surface

Call the same day. Do not wait until tomorrow to see if it gets worse. Earlier evaluation means better outcomes.

Dog Bites in Children

Dog bites are the most common animal bite children experience, and most of them come from a dog the family knows: their own, a relative's, or a neighbor's. That familiarity is exactly why parents talk themselves out of a doctor visit.

A dog's jaw generates real crushing force. What you see on the surface can be the small part of the injury, especially on a child's hand, where tendons and joints sit close beneath the skin. Follow the four steps above, and call your doctor the same day.

If the dog is your family pet, the vaccination conversation is easier, but the infection risk is unchanged. That is the part parents most often underestimate.

Cat Bites in Children

This is the bite parents are most likely to dismiss, because a cat bite can look like nothing. Two small dots on the hand. No bleeding to speak of. Meanwhile the puncture carried bacteria deep under the skin and then sealed over the top of it.

If a cat bit your child, especially on the hand, call the doctor today. Not tomorrow.

Signs of Infection to Watch For

Even after a doctor visit and proper care, infections can develop. Check the wound daily for the first week and watch for these warning signs:

• Increasing redness or swelling around the wound that is spreading rather than improving
• Warmth spreading beyond the wound edges
• Pus or discharge from the wound
• Red streaking moving away from the wound toward the body. This is a serious warning sign that needs same-day medical attention
• Fever, chills, or your child seeming unwell in the days after the bite

Wild Animal Bites: A Different Level of Urgency

A bite from a raccoon, bat, fox, skunk, or other wild animal is a different situation from a household pet bite. Wild animal bites carry a rabies risk that household pet bites generally do not, and rabies is one situation where timing matters enormously.

If your child is bitten by a wild animal, call your doctor or go to urgent care the same day. Do not wait to see if symptoms develop. The rabies post-exposure series needs to be started within a specific window to be effective, and your doctor will assess the risk and guide you from there.

Bat bites deserve special mention. Bat teeth are small and a bite mark may not be visible. If your child was in a room with a bat and you cannot confirm they were not bitten, that warrants a call to your doctor.

Which Animal Bites Always Need a Doctor

The answer is all of them, but these situations are especially important to get evaluated the same day:

• Any bite from a cat, regardless of how minor it appears
• Bites to the face, head, or neck
• Bites to the hand, fingers, or over a joint
• Any wild animal bite
• Any bite where the animal's rabies vaccination status is unknown
• Bites in children with diabetes, immune system conditions, or who are on medications that suppress the immune system
• Bites that are deep, jagged, or won't stop bleeding with pressure

A Note on Tetanus

Animal bites are a puncture wound, which means tetanus is on the list of things your doctor will review. Most children who are up to date on their routine vaccinations are covered, but your doctor will check. If your child's tetanus vaccination is not current, they may recommend a booster. This is another reason the doctor visit after a bite is not something to skip.

Common Questions from Parents

How long after a bite does an infection start?

Sooner than most parents expect. Infection often begins within the first day after the bite, and cat bites tend to show signs faster than dog bites. The timing varies, which is exactly why the doctor visit happens the same day rather than after a few days of watching. Check the wound that evening and again the next morning, and call if anything is spreading.

Our dog bit our child but he is fully vaccinated. Do we still need to see a doctor?

Yes. The dog's vaccination status affects the rabies conversation, but it does not change the infection risk from the bite itself. All dog bites should be evaluated by a doctor, especially puncture wounds and bites on the hands or face.

The bite did not break the skin. Do I still need to do anything?

If the skin is fully intact, infection risk is minimal. Wash the area with soap and water, watch for bruising or swelling, and if anything seems off, check with your doctor. Bites hard enough to leave significant bruising on young children are worth mentioning at the next visit.

Should I try to clean inside a deep puncture wound?

Run water over and around it and let the flow do the work. Do not probe inside a puncture wound with cotton swabs or anything else. Let the doctor handle the deeper cleaning.

My child was scratched, not bitten. Does that need a doctor visit?

Cat scratches in particular should be watched closely. Cat scratch disease is a real bacterial infection that can follow a cat scratch, not just a bite. If redness, swelling, or a swollen lymph node develops near the scratch in the days after, call your doctor.

Does a bite on the hand matter more than a bite somewhere else?

Yes. Hands have tendons, joints, and tight tissue spaces just under the skin, so a puncture there carries a higher risk than the same puncture on a forearm. Bites to the hand, fingers, face, or over any joint should be seen the same day.
