The "torture" will come later when the baby starts crawling & walking & chasing the dog & the parents will be all "aww look at that, that are best friends!" Then the child gets bitten, dog gets dumped at a shelter, now with a bite history or worse, PTS.
My dogs are used to kids crawling on them, bopping them on the head, pulling their ears and tail, taking their toys away, chasing them around.... and they have never bit. Or showed any sort of inappropriate behavior.
It's a little bit of a stretch to assume that all dogs are going to react to kids in such a negative way. Most dogs live with children and everyone copes just fine. Sure, a baby might stress a dog out sometimes - who doesn't get stressed out by babies? - doesn't mean the dog is going to lash out over it.
The parents that filmed the video know their dog way better than we do.
