Being attacked by a dog can be really scary, but if you stay calm and avoid sudden movements, the dog should lose interest in you. If an aggressive dog approaches you, never run or make a loud noise. This may scare him or he may chase you. Instead, stand with your arms open at your sides and look away from the dog. If it starts to bite or attack you, shout “back off” or “stop”. If he continues to attack you, try to hit or kick him in the face to stun him. You can also use your weight to your advantage by digging your knee or elbow into his groin or ribs. If you fall to the ground, roll onto your stomach and bring your knees into your chest to protect your vital organs. When the dog loses interest in you, slowly and calmly back away from the area until you are safe.
