Tools needed are a portable kennel, an electronic training collar, and a check cord.
The live collar is put on the dog’s neck and the controller is set to the lowest level. The proper way to place the collar on the neck is very high up, right behind the head. The collar needs to be tight enough to make good contact between the collar prongs and the skin on the neck. Then the nick button is pressed, and the dog is watched for a reaction. It could be a perk of the ears or a twitch. Move the level of stimulation up one level at a time until you can see a reaction. Once you can get a small reaction stop moving the stimulation level up. Dogs can really vary on how sensitive they are to the EC. Female dogs tend to be less sensitive than the male dogs.
Now the dog needs to learn how to turn the stimulation off. An easy and commonly used method is kenneling. Apply the low-level stimulation with the constant button. At the same time give the kennel command. As soon as the dog enters the kennel remove the stimulus. If the dog balks at entering the kennel, shove it inside. Make sure the dog is completely inside. They only way this works is if the dog understands that entering the kennel turns off the stimulus.
