I wouldn't take media shock statements as proof of anything though.
Either, the dog was alone in a kennel with a plastic shovel and may well have been trashing it in play.
Or, the dog was in a kennel with someone cleaning out that kennel, suggesting he posed no apparent threat, and he directed either frustration or aggression onto the inanimate object, not the human.
So it isn't quite the proof that you think it is, that this dog was by temperament, dangerous.
That he could be dangerous because of his size and because an accident at that size is far more serious than at dachshund or cockerpoo size is really not in doubt.
You realise, there are many major blood vessels close to the skin in humans - an accidental nick from a tooth even in play, from a smaller dog, can kill - even a toy poodle can bite through a chicken wing and bone - thats much MUCH tougher than a few mm of human skin.
Dogs (and much smaller than this one) have killed people accidentally, trying to rouse them from fits, strokes, collapses.
There are other incidents and fatalities that go much further to proving that some XL bullies are a very different problem, that we have not seen before, than this one does.
