They're the first ones off the top of my head... those breeds have physique and behaviour/ temperament traits that have also been deliberately selected for over generations, too.
Not a single one of these breeds automatically "knows how" to bite and maintain a grip... that is the result of selection in breeding for certain traits as well as long term training.
As for anxious Pitty's and crosses which are "physically capable and mentally predisposed..." you could quite adequately say that for over 95% of dog breeds. I've been bitten by numerous dogs, the vast majority being small breeds with a few Goldens, Labs and Border's thrown in for good measure.
Switzerland has numerous guns in all houses, their "accidental shooting" rate is lowest in the world.
Because people are educated to be careful with a gun whether it is an AK47 OR BB gun
I suspect the vast majority of dogs (again) have the potential when poorly trained and handled to become genuinely human or animal agressive with potential to cause serious injury. You cannot limit this to just one breed type!
This, however, is NOT consistent with the breeding purposes of a PitBull.
Of course, had you been an old lady or child, and this dog was, infact, a Golden Retriever, it would indeed have been reported in the papers and the breed reported as "Pit Bull".
In all honesty, CairnsVet, I'm of the opinion that you are simply continuing the propagation of hyperbole about the PitBull breed as opposed to acknowledging that the issues identified can and do exist in dogs in general and the only way to avoid attacks and problem behaviours is to educate people about the responsibilities of dog ownership, while discouraging the "idiots" from selecting breeds based on "what makes them look tough".
