The dog obviously did not think Tracy was in charge.
Here’s a gal that has control of her dog:

Very nice, amazing dog. Thought at first she was an extremely blocky black lab, having never seen an undocked rottie before.
Incidentally - you couldn’t pay me enough to take the badguy role for that test! (I notice he made a point of carrying the unprotected arm way high during the simulated detention perpwalk right next to the dog, LOL.) Not every dog’s gonna remain that under control during the entire exercise.
Awesome video.
What a good dog.
