I love dogs but this story doesn't surprise me - i am actually surprised there aren't more incidents of dogs hurting newborns, given how reckless people can be allowing their pets around their babies/toddlers.
When I had my daughter, it was the one period of my life I fervently wished we did not have our dog. The need to keep them separated at all times when not under direct supervision was exhausting, and made having a baby/toddler so much harder. But it was necessary. Even the kindest dog can turn at any moment - it can be injured, it can have an undiagnosed brain tumour..... And I have been told, and always believed, that newborns sometimes cry at a pitch dogs find unbearable to listen to, which can also trigger even loving dogs to uncharacteristic responses.....
And frankly, why would you risk it?
Yet you see these posts on Facebook with babies lounging all over someone's Belgian Mastiff or swinging off its tail (I exaggerated, but only slightly). I even know people who have deliberately got a puppy upon realising ther are pregnant, so that the two can "grow up together"..... Incomprehensible to me.
I think ideally, dogs and small children shouldn't be mixed at all - but obviously sometimes people get their dog or dogs (like I did) before they realise they may decide to start a family. In that case, extreme care needs to be taken to avoid tragedies like the one linked to above.
It isn't really about breeds in this case. At the end of the day, dogs are carnivorous predators, and they don't necessarily understand that a baby is human; not do they have a concept of murder and its ethical connotations. When q dog kills a baby, it's tragic, but there is a human to blame somewhere along the line..,..
