if I'm in the woods and some damn dog comes up to me snarling and what not i give him 5 feet, if he breaks that barrier he's toast. i work in the operating room dude. dogs bites are nasty and a bulldog could take a nice piece out of you let alone make you miss the rest of the season possibly. warn the owner in a professional manner, if he won't listen tell him you warned him. deer-hunter18 has an idea, befriend him and then teach him to drive deer
