How can you accuse someone of being utterly incapable of understanding statistics and making informed risk assessments and then come out with things like this? I'm guessing children a) walk on pavements and b) spend time in the bath a hell of a lot more often than they are in contact with Staffordshire Bull Terriers.
What part aren't you grasping?
Firstly, there isn't one death a year from Staffordshire bull terriers. There is an average of one death a year from dogs.
As countless people have pointed out, staffies are the most popular/populous dog in the UK, and yet don't make it into the top 10 of dog attacks, so how on earth you're extrapolating dog attacks with staffies, I have no idea.
But back to your original (illogical) point. A quick google tells me there are about 500,000 staffies in the UK. I'm going to guess most of these are the only staffie in the household, so lets say there are 450k households with a staffie. I'm going to further guess that if staffie owners are about average, about half of those will live in houses with children, because about half the households in the UK have a child living with them.
So lets say about 225k staffies living with children, or 600k children living with staffies.
I can find evidence of 4 children killed by their pet staffie in the last 12 years.
So crudely, that means about a 0.0004% chance of a child living in a house with a staffie being killed by that staffie.
How that can be considered a 'significant risk' by anyone is beyond me. It just isn't... It is up there with 'being killed by a vending machine' sorts of likelihood.
But back to your other clunky point about bathtimes vs time with a dog.
Pretty much everyone on here has said that children and dogs need permanent supervision when they are in the same room. Just like children need supervision in the bath
From my skim reading of press reports of dog attacks, children weren't being closely supervised. I'm going to go out on a limb and guess children drowning in baths weren't being supervised either.
So this is a supervision problem, not a dog problem. But even then, left unsupervised, baths are statistically more dangerous than staffies.
