What to do … if you are approached by an unknown dog?

If you or your child is approached by an unknown dog, do not run away. The dog’s prey drive will cause him to give chase. Do not make eye contact with the dog; he could interpret staring as a canine sign of aggression. Instead, stand still with your arms at your side, or back away slowly and quitly. In a loud, commanding voice, tell the dog to “Go away!” If you are attacked, give the dog an object such as a jacket or backpack to bite. If you fall or are knocked to the ground, curl into a ball. Protect your face by covering your head and neck, and put your hands over your ears.
