Being attacked by a dog should be one of our greatest fears. You may not be able to avoid being chased by a dog, but you can understand the "dog mentality" so that you can deal with it tactfully.Understand the nature of dogs,know the dog's tactics,keep the front wheel.If all else fails, get off your horse, put your bike between you and the dog, swing it as a defensive weapon if necessary, and call for help.If you have been bitten, report it, noting down the location, the time, the face of the dog, and even the owner's name and address.
