It's a controversial topic among dog trainers and dog owners alike. Whether to use an electric collar or not. First of all, most trainers and dog owners who use an electric collar do not like the words shock collars. Although that's what an electronic collar does, deliver a small electronic shock to your dog or puppies, it's not like your dog or puppies have entered a prison and are being administered a near electric chair shock voltage experience. Electronic collars are much gentler than that and can be an invaluable method of training your dog.
