As Beloz has said, the NSW statistics on dog attacks are a little short on detail. With the exception of the poorly defined 'under control' details, there is not any detail about the circumstances surrounding the attacks. Without knowing the individual circumstances, the NSW dog attack stats become meaningless lists.
Even such basic information as whether the dog was tied to a point, or whether the dog was guarding puppies, or even if the dog was in someway provoked are totally ignored by these sorts of lists. If I was going to be cynical about the NSW reports, I'd suggest that the stats are being kept in such a way to give support to and justify government policies. If I owned a Staffordshire Bull Terrier in NSW (as 1 in 20 dog owners do) I'd be very concerned right now, as these stats are painting the government into a corner.
The APBT is the best of the best dogs (but it is just a dog, like any other breed of dog)
