Remote dog training collars or “shock collars” as they are commonly referred to are easy to use and very safe and effective when used properly. Most of the shock collars use a warning tone then a vibration and then, if necessary, a slight stimulation. They can be used to protect your dog from dangerous situations as well as behavior correction and are only effective when used immediately as the correctable behavior is exhibited. When training, be sure to praise your dog and reward proper alternative behaviors.
