Good question. The dog that bit me knew me. I was in that yard with my friend playing on the swing set often. He was a bord dog too. It was weird.How in the heck did all you guys manage to get bit?? And about the head and neck, too?? I was around what could only be called high risk dogs all my childhood and young adulthood, and have NEVER been bitten by a dog. Cats, though ... THAT'S a different story ...
