Oh FFS I hadn't even watched it and now that I have, any excuses that it's training are flat out ridiculous. For one, the first time she hits it across the head, it's for
not falling for the prank she wants to make a video about. That simple. It doesn't even misbehave - it just doesn't walk into the clingfilm "trick" and tries to jump over it instead, so she smacks it in the face.
Then she physically
pins it to the floor for trying to lick her and the way she looks at it

... and then at the end she shoves it off camera (again, for licking her) and then quite clearly in the reflection hits it several times.
"Training".
