Yes, I know. Some of you are wagging your heads. Not my dog! Oh, I have heard it before. 10 years ago, I was running with my young sons riding bikes next to me through a quiet, polite sort of neighborhood. Suddenly, the largest dog I have ever seen came running out of the house like a missile toward me, knocking me over and biting me on the arse. As I sternly backed the monster down, I saw the backs of my boys already a quarter mile down the road pedaling like mad.
