Bad dog owners are a huge problem. Many problems seem to occur when 2 dogs, run together, and there's a child around.
I only ever been bit by a German shepherd when I was out jogging. It bit my left butt cheek and it hurt like fuck
This year I've been chased by dogs when running three times, now I just turn around and run towards the dog, they usually get scared and run away. One time I chased the dog into the woods, I find the owner listening to IPod totally unaware that his dog had run away. I wanted to waste him.... People who have no control of their dogs, should be mega-fined!
