Certainly the dog was trying to herd cats, but the cats didn’t really seem to be on board. The moving cat seemed confused as to why this dog suddenly wants to be the alpha.
The cat allows itself to be herded a bit, then realizes that the dog, whom it knows very well, is not going to enforce his herding with barks or snaps, and so the cat goes about its merry way.
The dog has an innate need to do this behavior, and the cat, not being truly threatened, knows it will always run the show,
So, yes, the owner needs to give the dog more things to do. You can’t just have a border collie lie around and be a lapdog. You shouldn’t own a working dog if you can’t keep it occupied.
