 Dr. Heinz and welcome to the Bark and Hold or Revere, we call it, instructional video. What is the Bark and Hold or Revere? It's when you send your dog to a person and the dog sits there and barks at them, threatens them without biting them, unless necessary, unless there's an action of aggression towards the dog, or a flight the dog is not supposed to attack, just goes running up to them, threatening them, scaring them, just in case. People use it for when they come home, they're not sure, they want to search the house before they enter. That was the Bark and Hold Revere video, there's a lot in here for you, I'll put bonus material too, so it is jam packed with information.
