Unfortunately, the public outrage is pretty high but not high enough for this woman. If you view the video clips at the link you'll see the outrage is pouring in, but the lady is just hiding behind her locked door. Maybe picketers at the foot of her driveway would change her mind.
I am guessing she won't change her mind but the people who got the dog will. A simple way to handle the kids is to ask the television station to do a piece on this man and his dog. Have the kids watch it and they will want do the right thing.
