Thats not an attack shes waggling her tail.

what an amazing animal absolutly lovely dog

They probably just put attack mode to get more views.

Notice the dog bow hind end up its a submisive posture meaning lets play.

you can tell that she’s playing. jumping down on her front paws, her ears are alert rather then pulled back, the fur on her back is completely smooth, not standing up, her tail is relaxed and waggy instead of being stuff and raised, she’s far too jumpy and her facial expression is that of eagerness, not aggression. beautiful dog
