It is not acceptable to use a shock collar on a dog and call it "training". It is beyond insulting to me, my colleagues, my mentors, my industry. It infuriates me to see it time and again. How anyone can think that sending an electric current through a dog's neck or genitals is an acceptable way to teach another sentient being how to "behave" is beyond me. It's the person holding the remote who needs to learn how to behave appropriately, as far as I'm concerned.
