Dogs are pack animals, so long as they know their position in the 'pack' of your family the child should be at no real risk from most dogs. Dogs with a violent temperament and dogs that are known to be violent without warning ie. Pitt Bulls/Rottweillers/Dobermanns should be kept away from children. But Great Danes/Newfoundlands/Lurchers/Greyhounds are big dogs that are often less violent than smaller breeds.
