I just watched this
and noticed that the dog NEVER wags her tail once during this. Maybe a tiny one here and there? I dunno... but I can't see.
When Jackson is doing stuff with me, he's constantly so happy and wagging his little tail, or at least moving it. You can see his body language.
If you look closely, you can really see the difference. Wow... I honestly had not watched that full Minnie Misa video til now.
