Early dog training, 1940s -- Film 90352

Dog Training. A man in his seventies trains three alsatian or german shepherd dogs. From the body language of the dogs the training must be harsh as all 3 dogs are obviously terrified of the trainer. First dog is sent to fetch a bucket of water. He retrieves the bucket then lies at heel. Second dog is sent over 3 jumps. Then does the high jump. Dog climbs a wooden wall eleven feet high and clears the top and jumps down the other side. Third dog demonstrates attack training. (most bizzare sequence).
