Spot onAfter over 20 years of training dogs, I have found that the more dogs I train and the more time goes by the less force and correction I use in my training. Katie has been corrected nearly NONE. I begin puppies now with NO collar or lead and teach them to follow along with me using praise, food, and marking with the clicker and then once they have learned I add the collar and leash.
It is my personal opinion that it is not fair to use force or inflict pain on a dog who does not clearly understand what he is being asked to do. I NEVER use force, correction, scolding etc, when I am teaching a dog something new. This includes corrections with any sort of collar. I simply don't find it necessary to get what I want from the dog. And what I want is sharp precise obedience given to me with the utmost of willingness and attitude.
