dog attacks are rare. like someone said before theres no bad dogs,just bad owners. i dont think its neccesary to shoot a dog,and if it was my dog that was shot well(which hed never would cause he's a good boy <img src="/images/graemlins/grin.gif" alt="" />) id have to kill someone. if u had some food you could distract him, ive been bit by dogs before by accident and i lived, its not like your gonna get killed unless its Cujo or ur a wuss(sorry for lack of better word). try consulting with pro's or vets ,my vet has told me what to do in case of a attack.
