Kind of dumb because we are here talking about very small baby and what seems to be a puppy of napoletan mastiff. So that big puppy could very easily crush the baby under him/herself. It not wise to let so big dog go over any people because they would learn that it is approven bahavior. It's domination at the same time, the dog sees it's appropriate to dominate children. Not good. That'll lead to the dog biting the child or even killing the child. It looks like the puppy thinks the child is a toy of his/hers. Not good at all.
