You sir have never bern attacked by a dog when they do go for you and this is from expetience.  I was pulled off my sled and on the ground on my back in a blink of an eye. My throat is still here because it was really cold and had talked me into wearing a huge scarf wrapped around my neck five or six times.  My dad took the dod off of me and killed it within about 8 or 9 seconds oterwise i might not be here today.
