What do you want people to say? You can't hear the guarding over the music. It is like a high-lights reel but there are a lot of problems still shown, so it makes me curious what they cut from the video. If they show that many problems what is it that they decided not to show? There is no obedience, many, many,many dogs can bite and work well without having to deal with a handler who demands that they are obedient.
Is the dog titled? Where is that video?
