I got bitten by a dog that looked at me from six meters away when I came out of the owner's car (with the owner driving! We were chatting amicably at the time), then with no other warning than standing very still for two seconds ran at me and bit my leg to the point of bleeding. Then, when I met it again three years later, tried to do the same thing but by that point they'd wised up and anchored its leash to something. Although, you know, maybe there existed a more constructive solution. And my cousin was bit three times (required stitches) by a dog she never approached, and backed away from carefully after it became obvious that it was unfriendly, running away after it bit her the first time. She did accidentally enter the owner's property, though, while jogging. The property boundary wasn't marked. I don't think you can generalize this stuff, unless you've made a detailed survey of the conditions concerning situations where dogs have bit people.
