The owners of the dogs euthanised them after the attack but no doubt they too will be forever haunted by the savagery of their pets.
In the wake of the Murupara attack, Local Government Minister Paula Bennett says she is considering whether dog control regulations need to improve.
The attack has also prompted calls to ban certain breeds of dogs. I initially agreed. However, while I believe some dogs are inherently more dangerous because of their ability to inflict damage, it is too late for such legislation to be effective because of cross breeding.
The best we can hope for is that people who insist on telling us their breed of dog is safe will reassess the risk-benefit of children sharing the same space as these animals.
Disturbingly, it usually falls to children to prove our faith in an animal's nature is misguided and that dogs of any breed can attack in certain circumstances.
If there is one thing we can take from this, it is that small children should never be left alone with dogs.
