FALSE:

The stimulation provided by an e-collar is a static shock, just like what you have probably experienced on a dry winter day. It is annoying but not painful, and it is designed to get your dog’s attention, it will not hurt your dog.

There are different levels of stimulation to choose from, and you should use the lowest one to which your dog responds. Modern e-collars are equipped with safety instruments to protect your dog from a prolonged or dangerous shock.

You can also use audible tones and vibrations instead of the static shock setting. Used correctly, an e-collar will not hurt your dog.
