If that kid ever comes over again, Hide the dog!! Put the dog in the bedroom or something. There is no excuse for what he did. He is not a baby who doesn't know any better. What is wrong with him. Thank goodness your baby wasn't physically hurt. She will come around, just keep trying to pet her and once she sees she won't be hurt she will trust again. Give her a big hug from Coco Pebbles and Trixie. That big fresh bully!!
