We need to show our dogs how to live peaceably in the world. Most dogs—of all breeds—can be trained to, although dismayingly few are. But some dogs simply can't be, for reasons of poor breeding and genetics, trauma in the litter, past abuse or training. Those dogs ought to be removed permanently from society, not recycled again and again. The violent dog epidemic is—or ought to be—morally untenable for those who see themselves as advocates for dogs.
We have lost our moral perspective when we don't recognize that the rights, safety, and welfare of children take precedence over even our most beloved pets. If any of my dogs ever bit a child and caused serious injury, I would seek a different, safer environment for the dog or, more likely, put him or her down, unwilling to ever take the chance that it might happen again. It wouldn't matter whose fault it was, if anyone's.
I told Jan that I was very sorry. But I couldn't help. Spice was euthanized.
