Over the past few years pet dog trainers have promoted the concept of no compulsion what so ever in their training. After thirty plus years of training dogs that must respond to commands regardless of the circumstances the belief a dog can learn to be obedient without the use of any compulsion is not accurate.
Electric trainers reduces the number of trials needed for the dog to learn. It delivers the same stimulation trial after trial and takes out the human emotion that causes the correction to vary. Studies have shown the most effective time for pairing a reinforcment with a behavior is immediate or not to exceed 1/2 of a second. We cannot administer a correction that fast without the aid of an electric trainer.
In most training the intensity that causes dog to jump, or yelp is too high. The goal is not to teach one trial learning but to provide a disconfort that puts the behavior into extinction. When use correctly it provides extinction latent. Extinction latent means preventing a response using mild pressure. Research has proven when extinction latent is use it is more expedient then using pure extinction.
I have trained 100’s of police dogs using an electric trainer. The time needed was reduced by about 30%, and not one sign of adverse behavor from the dog. As a matter of fact dogs seemed to have a better bond with the trainer.
