Fred Hassen, CEO of "Sit Means Sit" dog training, is shown here through an entire first session of training with a people aggressive dog. The audio on the camera was not working for this video, with the exception of the last 30 seconds of the dog training session, but as you can see, there is no talking to the dog verbally through the entire session, with the exception of our "non-verbal" communication, which you have also seen used successfully with "Sit Means Sit" dog trainers in the training of deaf dogs. The process of putting on the muzzle was omitted from this video for the purpose of time, and the dog training video picks up right at the moment where Fred Hassen has taken the dog from the owners, and they have put the muzzle on. You can see Fred actually testing again for the muzzle tightness, as it is obvious that it's going to be a bit of a battle of wills for awhile. This entire process is one training session, edited a bit for time purposes only. Locations Los Angeles, Phoenix San diego
