weight and intelligence to the contrary, unless you carry a gun, i think the advantage still goes to the dog.

Apparently (I don't know if this is true) you can kill any attacking dog by grabbing it's front legs and pulling them apart. This will pop the dog's heart open. Apparently.

But yeah, even without that (probably untrue) factoid and without a bat or a gun, I would make any dog that attacked me severely sorry. I'm sure I'd end up in hospital but I'd make bloody sure I didn't come off worse. I may lack the animalistic "killer instinct" but 101kg and a pair of size 12 stompin' boots goes a long way to making up for it...
