THIS IS A TRAINING VIDEO....This is a scenario when a K9 police dog is getting sent to stop a criminal and the criminal surrenders when he sees the dog coming for him. At that point the officer has to be available to stop the dog and give a new command that is asking to do the hold and bark....this means the dog is stopping in front of the suspect and barks in a aggressive manner. If the suspect moves or runs at that point the K9 will reengage the bad guy with a bite. This is high level training because the K9 dog has to execute the command in a fraction of a second ...there is no room for errors....it is not easy for the dog to stop himself from biting the bad guy/criminal ....how I define it is putting a switch into the dog with a remote control.
