A Jack Russell killed a baby while it was left unattended with the baby. It was in the UK. I remember it distinctly because I had a baby and a JRT at the time, although I never left them alone together.
I grew up around dogs, as did my children, and as DD19 currently has 2 very young chihuahuas who can live for up to 20 years I imagine her kids will be the same.
For me, it's a case of weighing up the benefits and risks. I can't imagine life without a dog. I suffer from depression and the dog gets me out daily. There's also the companionship, stress relief, and opportunity to teach kids responsibility and how to care for other living beings.
I didn't have a large breed when my kids were young. After my JRT passed we had a JRT/Westie cross and a small lurcher/Italian greyhound cross. We currently have a rottweiller cross but I didn't pick any of those dogs. The terrier cross was from the rescue I volunteered with at the time as a behaviourist/trainer and the lurcher was left on my doorstep.
We got the rottweiler cross when I posted on a local rescue page listing what we were looking for in a dog and he was the closest fit. I'd have anything from a chihuahua to an Irish wolfhound as long as it fit my requirements.
I have nothing against large breeds and frequently took in lurchers and greyhounds who needed teaching how to live in a home after a life in kennels and thought nothing of letting my children visit their grandparents who had an Akita and a Lab when they were young and later adopted a bull lurcher from my rescue.
All of these attacks have one thing in common and it's not the breed it's an irresponsible owner.
