He then takes out a wooden stick, and appears to show the camera person how to hit the wolf near the head. "He's very afraid of it," someone who appears to be a worker says, before Hackenberger shushes him.
A wolf can be seen pacing nervously in the background, apparently shut in a tiny kennel.
Later, an administrator of Bowmanville Zoo, the Ontario, Canada, facility Hackenberger co-owns and where the footage was filmed, can be heard talking about the trainer's violent methods.
"You throw them down on the ground so they know who's boss," the administrator says. "That's basically Michael's way of working all animals."
