An injured dog may bite anyone nearby. A dog fight can be violent and is upsetting to everyone present. Keep calm. Even the calmest, most pleasant, well-adjusted person may become upset, angry or belligerent, if they or their dog is injured in a fight. Emotional behavior is automatic; try to remain calm and as objective be as possible. Never reach your hands into the middle of a dog fight. You may get bit, and often by your own dog.
Distract the dogs and divert their attention. A blast of water from a water bottle, a loud whistle, or a pocket air horn may work. If your dog is not in the fight, make sure he/she does not join in. If a fight occurs, control your dog and remove him/her to a neutral area. Maintain a cool head. Getting upset and yelling will only add to the frenzy.
When warranted, exchange contact information with the other dog owners. If you can’t because you must attend to your dog, designate someone else to get information. Remember, owners are solely liable for injuries or damage caused by their dogs. This includes injury to another dog or person, no matter how it began, who said what, or whatever.
