If a dog bites you, tell an adult right away. Never leave infants or young children alone with any dog. If possible, restrain the dog and confine it. If the dog is not yours, try to find out where it lives or be able to describe it to authorities. Wash wounds with soap and water for one minute.
Serious infections are a risk with any animal bite.
If it is not an emergency situation, call your child's doctor to find out how the injury should be treated. Call 911 if emergency help is needed. Apply pressure to stop bleeding. A pediatric plastic surgeon may be needed. This will help make them less aggressive.
