Best trainned dogs for protection

Ivan Balabanov's Premier Protection Dogs overview of various stages of training and dogs.
Few notes that may be helpful and answer the most FAQ:
*The Ferrari did not get hit with the stick :)
*The guy at 3:20 is attacked on command and direction of the handler. It is training exercise where the dog has to be guided ... even to a person who appears not to be a danger on first sight.
*3:44 the same thing, it is not about being dead, but not going to attack without the handler allowing it to do so. Strictly for training control. In real situation this will be handled very differently.
Hope you enjoy the video as it is just a sample of training
