Animal and human bites may cause puncture
wounds, cuts, scrapes, or crushing injuries. Most animal and human bites cause
minor injuries, and home treatment is usually all that is needed to care for
Most animal bites occur in school-age
children. The face, hands, arms, and legs are the most common sites for animal
bites. Since most bites occur in children, be sure to teach children to
be careful around animals and that an animal could hurt them. Young children
should always be supervised around animals.
Dog bites occur more than any other animal bite and are most
frequent in the summer months. The dog is usually known to the person, and most
injuries result from the dog being teased or bothered while eating or sleeping.
Boys are bitten about twice as often as girls. The arms, head, and neck are the
most likely areas to be bitten in children.
Cat bites usually cause deeper puncture wounds than dog bites
and have a high risk of bacterial infection because they can be hard to

sheep, have powerful jaws and can cause crushing bite injuries. Infection,
tetanus, and rabies are possible risks.
Wild animal bites may occur while hunting,
camping, or hiking. Infection, tetanus, and rabies are possible risks.
Adult bites that cause a wound to the
hand can be serious. A clenched fist striking another person in the mouth and

To clean a wound well:
If a chemical has caused a wound or burn, follow the instructions on the chemical's container or call Poison Control (1-800-222-1222) to find out what to do. Most chemicals should be rinsed off with lots of water, but with some chemicals, water may make the burn worse.

Some bites cause only bruising (contusions) at the bite site
but do not break the skin. These bites usually do not become infected.
Determine whether your bite needs to be treated by a doctor.
Bites may need to be closed with sutures, staples, or skin adhesives so that
they won't leave a large scar. Bites to the hand are not usually closed because
closing the bite wound may increase your chance of having an infection. Cat
bites are rarely closed because they are usually no larger than a puncture.

Skin adhesives usually do not need to be removed, but your doctor may wish to
see you to check on the wound. Be sure to carefully follow your doctor's
instructions. If you are unsure of how to care for your wound or have
questions, call your doctor for instructions.
Most bites heal well and
may not need a bandage. You may need to protect the bite from dirt and
irritation. Be sure to clean the bite thoroughly before bandaging it to
reduce the risk of infection occurring under the bandage.

directly to a wound or the skin. This could cause tissue damage.
Elevate the injured area on pillows while applying ice and anytime you
are sitting or lying down. Try to keep the area at or above the level of your
heart to reduce swelling.
Talk to your child's doctor before switching back and
forth between doses of acetaminophen and ibuprofen. When you switch between two
medicines, there is a chance your child will get too much medicine.
Many states require that animal
control authorities be notified of animal bites. Even if your state law does
not require you to report animal bites, you may wish to call animal control to
report the bite. They can help you determine whether the animal that bit
