To pin my colours to the mast, I'm not a dog lover (not a hater either - I'll give friends' dogs some fuss and agree they can be very appealing at times) and have never owned one as an adult (had one briefly as a child, but then my father's job took us abroad for a few years so we decided that it was kinder to re-home her with the next door neighbours than take her to a hot climate and then put her through quarantine when we returned).
However, I don't think I've ever read an instance of a dog seriously biting/mauling someone when they haven't been described as always being a big softy, fine with children etc.
The daughter of the woman who was killed recently said that her children used to use the dogs as pillows.
Three first hand experiences have made me very wary.
My grandmother's corgi bit my hand badly when I was walking past her. Just me in the room (about 7yo), dog lying on the floor and I was going to the kitchen. Tbf, she was known to snappy and hhad given "nips" so I never touched her.
I guess I'll never know why she suddenly leapt up and bit my hand.
Luckily, I got the use back in it after an operation (but the hospital stay was no fun for a child).
Another was a friend's daughter's dog (Cavalier King Charles) who was lovely, brilliant with children and so forth.
Until he suddenly turned on my friend's grandson (offspring of the lady who owned the dog) when he was a baby lying in a carry cot on the sofa.
Poor child ended up with some awful facial scarring.
Lastly, MiL used to breed guide dogs and had previously bred another breed for 30 years. So knew her way around dogs.
One of those attacked the postman when he was handing over a parcel - enough the rip his trousers and draw blood.
So maybe I'd describe myself as not a dog truster.
I know people get great joy from their dogs and the vast majority of dogs never bite.
But this one has and I would never have it around children again myself.
