Dog bite prevention training is for workers who enter yards or homes where dogs may be present. That includes letter carriers, meter readers, utility technicians, code enforcement officers, inspectors, home health aides and delivery drivers. The 20-minute video is available in English and also covers first aid for bites.

Warning signs that a dog may bite include a stiff body, raised hackles, a fixed stare, growling and bared teeth. Ears pinned back, a tail held high and stiff, or a dog that suddenly freezes are also red flags. A wagging tail alone doesn't mean a dog is friendly.

If a dog charges at you, stop and stand still rather than running. Avoid direct eye contact, stay calm and keep your arms close to your body. Put a bag, clipboard or other object between you and the dog. Once the dog loses interest, back away slowly while facing it.

For a dog bite, wash the wound thoroughly with soap and running water. Control bleeding with direct pressure and cover it with a clean bandage. Seek medical care, since bites often become infected and rabies risk must be assessed. Report the bite to your supervisor and local animal control.

Field workers can reduce dog bite risk by checking for dogs before entering a yard and rattling the gate or calling out first. Ask owners to restrain pets. Never reach over fences or into vehicles where dogs are present. Carry a deterrent if your employer allows it, and flag problem addresses.
