HAve they realised detail yet of why the dog did it and how well the dog was trained? If you want proof then perhaps you could offer proof for this too.
I do think it's a bit naive to assume that the only deaths this recent year from dogs are the 3 cases of teh rottweiler in the news. DOgs have been around for many years and no of course I dont have proof and frankly cant be arsed to look for it, but I think it's a safe bet to assume other breeds apart from rottweilers have been responsible for killing.
