I noticed the dog corollary too: dogs attack only when you're riding uphill or into the wind. The size of the dog is directly proportional to the grade of the hill or the wind speed. You should also add that the probability of a dog running directly in front of the bike is directly proportional to your velocity at the time of the attack.
