These dangerous, abusive collars should be banned in the USA and everywhere. UK Amazon.com banned these devices of torture, but Amazon stills sells them everywhere else. Amazon.com's USA and International web-sites must stop selling all pong collars and related devices used to train/torture dogs. Selling such items condones and contributes to animal abuse! We ask  Amazon.com to act responsibly and pull all such devices from their websites immediately, forever. We ask consumers to boycott Amazon.com until they remove these devices. Thank you for your support, dogs deserve far better! If we do not speak for them who will?
