Broke up a dog confrontation this evening. Was hanging out on my back deck when I heard animal whimpers and growling and people yelling. Went out front to find that one dog had clamped its jaws around the mouth of another dog and was not letting go. Remembered reading that hosing mating dogs is a good way to separate them. Went inside and got my Nalgene bottle of cold water out of the fridge and returned to the scene. A couple of good splashes to the snout did the trick. Got praise from motorists who had stopped to watch the whole thing as well as the owner of the aggressor. The other owner was understandably too distracted to thank me.
