Is this the narcissistic in laws that you hate and have caused you so much grief? Why are they even looking after your DS? Hell no would I leave my DS with them and their attitude and their dog. There is no rewind button and you can't rewind a dog that attacked and killed. It happends and its tragic and all we can do to honour those kids that were killed by a family pet is learn by it. No pet should be left unsupervised ever.
