When kids and dogs are in the same space, SUPERVISE, SUPERVISE, SUPERVISE. But all the supervising in the world won't stop the inevitable if you are just watching it happen. Step in BEFORE anything happens, even if you believe your dog and your child would never do anything to each other. Don't be dumb! Stop what COULD happen from becoming what WILL happen. Don't put all the responsibility to be good on your dog. Teach your kids to be respectful of the dog and teach your dog to give space to your kids. If you're too far away to remove the baby, call your dog away. If your dog is cornered, don't allow the baby or child to go anywhere near the dog.
Above all, be wise!!!
