I agree that you can never trust a dog 100%, but I think there is a lot you can do to make your kids pet aware. My dogs have always been supervised in their interactions with our kids. We have also ensured that our kids have a healthy respect for the dogs. Knowing how to pat them, keeping away from dogs when they are eating etc. I could leave the babies on their rugs when I left the room because I knew the dogs would always follow me LOL.
